Question

A bag contains 5 red balls, 6 white balls, 7 green balls, 8 black balls. One ball is drawn at random from the bag. Find the probability that the ball drawn is white

Answer 1

Sample space (S) = 5 + 6 + 7 + 8

n(S) = 26

Let A be the event of getting a white ball

n(A) = 6

P(A) = `("n"("A"))/("n"("S"))`

P(A) = `6/26 = 3/13`
