#### 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

not a black ball.

#### Solution

Total number of balls=3+5+2=10

Total number of events =p(n)=10

There are 3+2=5 balls which are not black

favourable number of event=P(A)=5

Hencwe, P (not getting a black ball)= "P(A)"/"P(n)"=5/10=1/2

Is there an error in this question or solution?
