Question

1. Q;Mia went shopping for new shirts,

there are two pink shirts, seven blue shirts, and four green shirts,

If she picks up some shirts,

how many different purchases could Mia make ? Please explain.

Answer 1

The answer depends on how many shirts she buys and whether she buys all different colors or some of the same color...and in order to answer the question you need to specify these parameters.

For example if she buys 3 shirts of different colors, she can pick the first shirt in 3 ways, the second in 2 ways and the third in only one way, i.e. 6 different sets of shirts.
