- Purpose of use
- If sample_1 and sample_2, each of length n, are chosen at random from a same list of N different integers, what are the probabilities to observe x = 0...n pairs of identical integers in both samples.
- Comment/Request
- I didn't realize at first glance that as soon as sample_1 is chosen at random, this set constitutes the M subset for an hypergeometric distribution: n = M in this problem.

- Comment/Request
- Can you add a way to calculate the odds of 2 different calculations put together, as in the chance of them happening at the same time? For example, let's say in a deck of 40 cards I want to calculate the odds of opening 1 6-of and 1 9-of in a starting hand of 5 together. I know that multiplying the odds together gets an approximate, but I want to see the accurate probability of these two events happening simultaneously.

- Purpose of use
- To decide the composition of a charity club membership working party comprising experienced members & other members so that the probability that at least one or more experienced member(s) would be included. This gave a cumulative >90% chance of the condition being fairly met.
- Comment/Request
- Worked brilliantly & reduced the arguments between members a) Those always doing the work b) Ensured greater participation.

c) Saved me having to do the math.

Love this program.
