There are 5 balls numbered from 1 to 5 in a box. A ball is picked from the box and placed back, then again a ball is picked. What is the probability that the product of the numbers on two balls is even?
let’s calculate when the product is odd = when both the numbers are odd = 3/5*3/5 = 9/25
hence when the product is even = 1-9/25 = 16/25
