The result which we can get just by typing the name of the variable is:. Now suppose we are rolling with disadvantage. To get a score at or above a given number we must roll that number or higher on the first die AND on the second die.

So the probabilities of rolling at or above 20, 19, 28, …, 1 with disadvantage are:. If we roll with advantage, we just have to roll at or above the desired number with either the first die OR the second die.

So we get:. We can assemble the results into a table easily enough. To generate a list of the target number for each probability, we generate the numbers from 1 to 20 and reverse them using.

We then combine all of our results with stitch ,. We could also add a key and axis captions easily, though this makes the line of code much longer:.

J has many other features that are very useful for statistical analysis, including least squares curve fitting.

Aber hier dazu eine Wahrscheinlichkeitstabelle. I know the potential for a higher total is there, but does that offer a flatter affect over a single d20 roll?

The second d20 increases the possibility of a pass at the lower targets than at the higher targets, and is inverse for disadvantage.

But how much better? Expected damage from two attacks is p. Translating this: yes, two attacks are always better. How much better varies on your chances of hitting — if you have a low chance of hitting, two attacks are a tiny bit better; if you have a high chance of hitting, two attacks are significantly better.

This is assuming that all attacks are equal; if the attack with advantage has higher damage, or stronger riders, than the two attacks without, that changes the maths.

The simple rule is probably to use the disadvantage rule. However, this is probably quite punitive according to other DMs that are clearly much smarter in math than I am.

Please check out their math and results here, here and here. If they miss, then roll again To Hit the friendly target, using the appropriately adjusted armor class i.

While there are still two rolls, other variables of hitting a different target, like armor, magical protection, etc.

Your table only goes 3 places past the decimal point, skewing the results. A significant difference. To calculate the chance of hitting an enemy, simple take their AC, adjust with modifiers e.

No tables or simulations needed. But if you like rolling lots of dice 4d10 choose 2 sounds more fun than 2d20 choose […].

What it means is that in 5e, rolling a d20 with disadvantage gives you a 0. Without advantage or disadvantage, you have a 0.

With advantage, you have a 0. Why is there a blank space there? Thanks for this! Came here to see my chance of having my concentration spell interrupted.

The Condorcet paradox also known as voting paradox or the paradox of voting in social choice theory is a situation noted by the Marquis de Condorcet in the late 18th century, [1] [2] [3] in which collective preferences can be cyclic, even if the preferences of individual voters are not cyclic.

This is paradoxical , because it means that majority wishes can be in conflict with each other: Majorities prefer, for example, candidate A over B, B over C, and yet C over A.

When this occurs, it is because the conflicting majorities are each made up of different groups of individuals.

Thus an expectation that transitivity on the part of all individuals' preferences should result in transitivity of societal preferences is an example of a fallacy of composition.

The paradox was independently discovered by Lewis Carroll and Edward J. Nanson , but its significance was not recognized until popularized by Duncan Black in the s.

Suppose we have three candidates, A, B, and C, and that there are three voters with preferences as follows candidates being listed left-to-right for each voter in decreasing order of preference :.

If C is chosen as the winner, it can be argued that B should win instead, since two voters 1 and 2 prefer B to C and only one voter 3 prefers C to B.

However, by the same argument A is preferred to B, and C is preferred to A, by a margin of two to one on each occasion. Thus the society's preferences show cycling: A is preferred over B which is preferred over C which is preferred over A.

A paradoxical feature of relations between the voters' preferences described above is that although the majority of voters agree that A is preferable to B, B to C, and C to A, all three coefficients of rank correlation between the preferences of any two voters are negative namely, —.

Note that in the graphical example, the voters and candidates are not symmetrical, but the ranked voting system "flattens" their preferences into a symmetrical cycle.

Candidate A gets the largest score, and is the winner, as A is the nearest to all voters. However, a majority of voters have an incentive to give A a 0 and C a 10, allowing C to beat A, which they prefer, at which point, a majority will then have an incentive to give C a 0 and B a 10, to make B win, etc.

In this particular example, though, the incentive is weak, as those who prefer C to A only score C 1 point above A; in a ranked Condorcet method, it's quite possible they would simply equally rank A and C because of how weak their preference is, in which case a Condorcet cycle wouldn't have formed in the first place, and A would've been the Condorcet winner.

So though the cycle doesn't occur in any given set of votes, it can appear through iterated elections with strategic voters with cardinal ratings.

Suppose that x is the fraction of voters who prefer A over B and that y is the fraction of voters who prefer B over C. It is possible to estimate the probability of the paradox by extrapolating from real election data, or using mathematical models of voter behavior, though the results depend strongly on which model is used.

We can calculate the probability of seeing the paradox for the special case where voters preferences are uniformly distributed between the candidates.

This is the " impartial culture " model, which is known to be unrealistic, [11] [12] [13] : 40 so, in practice, a Condorcet paradox may be more or less likely than this calculation.

Some results for the case of more than three objects have been calculated. When modeled with more realistic voter preferences, Condorcet paradoxes in elections with a small number of candidates and a large number of voters become very rare.

Many attempts have been made at finding empirical examples of the paradox. A summary of 37 individual studies, covering a total of real-world elections, large and small, found 25 instances of a Condorcet paradox, for a total likelihood of 9.

On the other hand, the empirical identification of a Condorcet paradox presupposes extensive data on the decision-makers' preferences over all alternatives--something that is only very rarely available.

While examples of the paradox seem to occur occasionally in small settings e. When a Condorcet method is used to determine an election, the voting paradox of cyclical societal preferences implies that the election has no Condorcet winner : no candidate who can win a one-on-one election against each other candidate.

There will still be a smallest group of candidates such that each candidate in the group can win a one-on-one election against each other candidate however, which is known as the Smith set.

The several variants of the Condorcet method differ on how they resolve such ambiguities when they arise to determine a winner.

Note that using only rankings, there is no fair and deterministic resolution to the trivial example given earlier because each candidate is in an exactly symmetrical situation.

Situations having the voting paradox can cause voting mechanisms to violate the axiom of independence of irrelevant alternatives —the choice of winner by a voting mechanism could be influenced by whether or not a losing candidate is available to be voted for.

One important implication of the possible existence of the voting paradox in a practical situation is that in a two-stage voting process, the eventual winner may depend on the way the two stages are structured.

For example, suppose the winner of A versus B in the open primary contest for one party's leadership will then face the second party's leader, C, in the general election.

In the earlier example, A would defeat B for the first party's nomination, and then would lose to C in the general election.

But if B were in the second party instead of the first, B would defeat C for that party's nomination, and then would lose to A in the general election.

Thus the structure of the two stages makes a difference for whether A or C is the ultimate winner.
