Answer #1

A grocery store is holding a raffle to give free shopping sprees to two customers.

Given that 25 customers who have entered the drawing.

Out of 25 , 10 males and 15 females

Probability that first winner is from males = 10/25

Probability that 2nd winner is from males assume first winner is male = 9/ 24

So probability that both customers selected at random are males is,

= (10/25)(9/24) = 0.15

Answer : Probability that both customers selected at random are males is 0.15
