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 is: 

not a red ball. 

Solution

There are 3+5=8 balls which are not red 

Favourable number of events= P(A)=8 

Hence, P (not getting a red ball) =` (P(A))/(P(n))=8/10=4/5`

  Is there an error in this question or solution?
