Question

A bag contains 3 red and 5 black balls. A ball is drawn at random from the bag. What is the probability that the ball drawn is not red.

Answer 1

SOLUTION :  

GIVEN : Number of red balls  = 3

Number of Black balls = 5

Total number of balls in a bag = 3 + 5 = 8

Total number of outcomes = 8

Let E = Event  of getting a ball which is not red  

Number of ball which is not red i.e black balls = 5  

Number of outcome favourable to E = 5

Probability (E) = Number of favourable outcomes / Total number of outcomes

P(E) = ⅝  

Hence, the probability of getting a  ball which is not red , P(E) = ⅝ .

HOPE THIS ANSWER WILL HELP  YOU…

Answer 2

Number of favourable outcomes =5


Total number of outcomes =8.


so, the probability is 5/8.
