Question

A sporting goods store received an order of 90 baseball caps, of which 18 were green. If 1 of the 90 caps is selected at random, what is the probability it will not be green?

Answer 1

`color(green)(80%)`

Explanation:

`90-18=72` of the caps are not green.
`rarr` the probability of selecting a "not green" cap out of the `90` caps is
`color(white)("XXX")72/90=8/10=80%`
