Amy has 12 brown golf tees, 8 white golf tees, 10 red golf tees, 6 blue golf tees, and 12 green golf tees in her golf bag. if she selects one of the tees from the bag at random, what is the probability that she selects a tee that is not brown or blue?

Add all the tees together and that is 48 so no we know the probability will be out of 48. There is 18 brown and blue tees altogether (12+6=18). Now, to work out the probability of selecting any other colour that those two we substitute; 48-18=30 and therefore the probability is 30/48 (30 out of 48)
