Question

6. A sporting goods store receives an order of 100 baseball caps, of which 22 are green. If 1 of

the 100 caps is selected at random, what is the probability it will not be green?
A. 39/50
B. 11/25
C. 11/50
D. 1/2

Answer 1

`\text{A. }39/50`

Explanation:

The probability that a randomly selected cap will not be green is equal to the number of non-green caps divided by the total number of caps.

Since there are 100 caps total and 22 are green, there must be
`100-22=78` non-green caps.

Divide this by the total number of caps (100) to get the probability that a randomly selected cap will not be green:

`(78)/(100)`

Simplify by dividing both the numerator and denominator by 2:

`(78)/(100)=\boxed{39/50}`
