A bag contains 3 red balls and 5 black balls. A ball is drawn at random from the bag.

What is the probability that the ball drawn is


(i) Red? (ii) Not red?


(i) Total number of balls in the bag = 8

Probability of the ball drawn to be red. :


=


=


(ii) We know that:


P (E) = 1 - P ()


Hence,


Probability of not getting red ball


= 1 - Probability of getting a red ball


= 1 -


=


8
