Figuring out possible combinations in math
WebIf the order doesn't matter then we have a combination, if the order does matter then we have a permutation. One could say that a permutation is an ordered combination. The number of permutations of n objects taken r at a time is determined by the following formula: P ( n, r) = n! ( n − r)! WebBasically, I calculated the odds of drawing 4 ones out of 36 cards, and multiplied that result times (9 choose 4), which is the number of ways that these 4 can be organized in 9 positions. 1. The probability of drawing the 1st one is 4/36. 2. The probability of drawing the 2nd one is 3/35. 3.
