The factorial of 10 would be written as 10!. For this calculator, the order of the items chosen in the subset does not matter. So the probability that Jim selects the correct passcode is 1/30,240. This problem will involve two processes: first of all, the use of permutations to calculate the number of passcodes that Jim could choose from, and secondly, the probabilities to calculate the chances of Jim selecting the correct passcode. This type of activity is required in a mathematics discipline that is known as combinatorics; i.e., the study of counting. = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1, and on bottom, 5! study

We can see that the probability of Jimmy selecting a red gumball from the bag is 20/47.
