A bag contains 3 red balls and 5 black balls. If A ball is drawn at random from the bag. Then What is the probability that the ball drawn is: (i) Red (ii) Back

Given that A bag contains 3 red, and 5 black balls. A ball is drawn at random

to find: Probability of getting a

(i) red ball

(ii) white ball

So, Total number of balls 3+5=8

(i) we know that Total number red balls are 3

We know that the Probability = Number of favorable outcomes/ Total number of outcomes

Therefore, the probability of drawing a red ball =3/8

(ii)  Now Total number of black balls are 5

We know that the Probability = Number of favorable outcomes/ Total number of outcomes

Hence, the probability of drawing a black ball =5/8
