Question

A bag contains 3 red and 8 blacks ball and another bag contains 5 red balls and 7 blacks balls, one ball is drawn at random from either of the bag, find the probability that the ball is red.

Answer 1

Total outcomes=23
Favorable outcomes=8
P(E)=8/23

Answer 2

Its 8/23
Total no of outcomes =23
Number of red balls 8
So, favourable outcomes =8
Probability of the event =P(E)=8/23
