Question

Three bags contain 3 red, 7 black, 8 red, 2 black and 4 red, 6 black balls respectively. 1 of the bags is selected at random and a ball is drawn from it. If the ball drawn is red, find the probability that it is drawn from the third bag.

Answer 1

Answer:

Three bags contain 3 red, 7 black, 8 red, 2 black and 4 red, 6 black balls respectively. 1 of the bags is selected at random and a ball is drawn from it. If the ball drawn is red, find the probability that it is drawn from the third bag.

Step-by-step explanation:

n(s)=3+7+8+2+4+6=30

let E be the event of getting a red ball from 3rd bag

n(E)=4

P(E)=n(E)/n(s)

=4/30
