Question

Neil and Jean each choose a number at random from the set 1,2,3,4,5,6,7,9,10 their numbers are allowed to be the same. What is the probability that the product of those two numbers is even?

Answer 1

Answer:

65/81

Step-by-step explanation:

In order for the product to be even, at least one of the numbers must be even. So the probability is 1-(prob that both are odd). The probability that Neil's is odd is 4/9, and the same is true for Jean. So the probability is 1-4/9*4/9=65/81
