Solution 1

The number of possible samples can be calculated using the combination formula, which is C(n, r) = n! / [r!(n-r)!], where n is the total number of items, r is the number of items to choose, and "!" denotes factorial.

In this case, the total number of items n is 6 (5, 10, 15, 20, 25, and 30) and we Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
