Question

A manager chooses 2 months of the year during which to have training. What is the size of the sample space in this experiment?

Answer 1

The sample space refers to all possible ways of choosing two months. Since we have 12 months to choose from, the number of ways would be

12C2

We are applying combination because the order of the months doesn't matter. From our calculator,

12C2 = 66

the size of the sample space in this experiment is 66
