Problem of the Week
Problem A
Summer Selections

Robbie is trying to simplify his summer wardrobe. He always wears a pair of shorts, a shirt, and a hat. He has:

• $3$ pairs of shorts in the colours of red, grey, and yellow

• $3$ shirts in the colours of red, white, and green

• $3$ hats in the colours of yellow, purple, and white

How many different combinations of a pair of shorts, a shirt, and a hat can he put together so that each item is of a different colour?
