Mike has a stack of 10 cards numbered 1 to 10 if he randomly chooses two cards without replacing the first one drawn what is the probability that mick would pick two cards that are prime numbers?

Respuesta :

4 out of 10 because the amount of prime numbers from 1- 10 is 

2, 3, 5, and 7.

Hope this helps!

In 1-10 the prime numbers are (2,3,5,7). so out of the 10 numbers you will pick 2 and and replace 1 so the total becomes 9 and the the prime numbers are 4 so it becomes 4/9
