In comments, discuss how the the 2 options (counting all the possible elements and using a formula) confirm the correct count of the relevant subset(s). WebUse the fact that log (a * b) = log (a) + log (b), and log (a / b) = log (a) - log (b). This makes it easy to work with very large factorials: log (n! / m!) = log (n!) - log (m!), etc. Use the …

WebThe general permutation can be thought of in two ways: who ends up seated in each chair, or which chair each person chooses to sit in. This is less important when the two groups are the same size, but much more important when one is limited. n and r are dictated by the limiting factor in question: which people get to be seated in each of the limited number of … Python has a package called‘itertools’ from which we can use the permutations function and apply it on different data types. The number of total permutation possible is equal to the factorial of length (number of elements). In our case, as we have 3 balls, 3! = 3*2*1 = 6.
