My own question:

You go to a party and there are 80 party favours in a bag. 5 are lasers, 10 are stuffed toys, 25 are kazoos, 20 are bags of candy and 20 are computer games. What is the probability of pulling out anything besides the kazoos?

The answer:

5 + 10 + 20 + 20= 55

As a fraction- 55/80

Percentage- 55 divided by 80= 0.6875

0.6875 * 100= 68.75%
