Question

A bag of tiles contains 6 green 4 yellow and 5 blue tiles. If one tile is pulled at random what is the probability of not choosing a green tile?

Answer 1

3/5

Explanation:

6 green 4 yellow and 5 blue tiles = 15 tiles

4 yellow and 5 blue tiles = 9 not green tiles

P( not green) = number of not green tiles / total tiles = 9/15 = 3/5
