(a) If the order of the choices is not relevant, this is a combination problem. The formula for combinations is C(n, k) = n! / [k!(n-k)!], where n is the total number of objects, k is the number of objects to choose, and "!" denotes factorial.

In this case, n = 15 (the total number of distinct objects) and k = 5 (the number of objects we want to choose).

So, the number of ways to choose 5 objects from 15, without regard to order, is C(15, 5) = 15! / [5!(15-5)!] = 3,003.

(b) If the order of the choices is relevant, this is a permutation problem. The formula for permutations is P(n, k) = n! / (n-k)!, where n is the total number of objects, k is the number of objects to choose, and "!" denotes factorial.

In this case, n = 15 (the total number of distinct objects) and k = 5 (the number of objects we want to choose).

So, the number of ways to choose 5 objects from 15, with regard to order, is P(15, 5) = 15! / (15-5)! = 360,360.

Suppose we want to choose 5 objects, without replacement, from 15 distinct objects.(If necessary, consult a list of formulas.)(a) If the order of the choices is not relevant, how many ways can this be done?(b) If the order of the choices is relevant, how many ways can this be done?
