A calculator is programmed to generate random integers from 1 to 80 inclusive when the button is pressed. What is P(multiple of 20) when the button is pressed one time?

0.05

Step-by-step explanation:

The Sample Space is that of numbers between 1-80 (both end numbers inclusive).

Therefore: number of elements in the Sample space, n(S)=80

Multiples of 20 are: 20,40,60 and 80

n(Multiples of 20) =4

The probability of obtaining a multiple of 20 when the button is pressed one time is:

P(Multiple of 20)

12*c

step-by-step explanation:

the answer is $42.96
