A bag contains a certain number of red balls. A ball is drawn. Find the probability that the ball drawn is: (i) black (ii) red
A bag contains a certain number of red balls. A ball is drawn. Find the probability that the ball drawn is: (i) black (ii) red

Solution:

We have,

Total possible outcomes = number of red balls.

(i) Number of favourable outcomes for black balls = 0

Hence, P(black ball) = 0

(ii) Number of favourable outcomes for red balls = number of red balls

Hence, P(red ball) = 1
