#### Question

A bag contains 3 white, 5 black and 2 red balls, all of the same shape and size. A ball is drawn from the bag without looking into it, find the probability that the ball drawn

a red ball.

#### Solution

Total number of balls=3+5+2

Total number of events =p(n)=10

There are 2 red balls

favourable number of events=p(A)=2

Hence,p(getting a red ball) = "P(A)"/"P(n)"=2/10=1/5

Is there an error in this question or solution?
