A bag contain 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 (a) red and (b) not red ?

Probability deals with finding out the likelihood of the occurrence of an event. Probability measures the chance of an event happening and is equal to the number of favourable events divided by the total number of events. Number of red balls = 3 Number of black balls = 5 Total number of balls = 5 + 3 = 8 (i) Probability of drawing red balls = N u m b e r o f r e d b a l l s T o t a l N u m b e r b a l l s = 3 8 (ii) Probability of drawing black balls = N u m b e r o f b l a c k b a l l s T o t a l N u m b e r b a l l s = 5 8
