A box contains twenty-five cards numbered 1 through 25. One card is to be randomly drawn from the box.


What is the probability that the card drawn will show a multiple of 5, a multiple of 6, or a multiple of 7?

A.12/25


B.9/25


C.3/25


D.1/25

Respuesta :

Multiples of 5 less than 25:  5,10,15,20,25
Multiples of 6 less than 25:  6,12,18,24
Multiples of 7 less than 25:  7,14,21
12 of the numbers are multiples of 5,6, or 7.  Your probability is 12/25
D because there is only one of each so you can only pick one of that card unless you put the card back in
