Answer 1

The number of ways for which she could pick four colours if green must be one of them is; 10 ways.

How many ways can she picks four colours if green must be there?

It follows from the task that there are 6 colours in total that she could pick from.

Hence, since she needs four colours with green being one of them, it follows that she only has 3 colours to pick from 5.

Hence, the numbers of possible combinations is; 5C3 = 10 ways.
