1.	A bag contains 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:(i) Red (ii) Back
Answer» Given: A bag contains 3 red, and 5 black balls. A ball is drawn at random Required to find: Probability of getting a (i) red ball (ii) white ball Total number of balls 3 + 5 = 8 (i) Total number red balls are 3 We know that, Probability = Number of favourable outcomes/ Total number of outcomes Thus, the probability of drawing a red ball = 3/8 (ii) Total number of black ball are 5 We know that, Probability = Number of favourable outcomes/ Total number of outcomes Thus, the probability of drawing a black ball = 5/8

Answer»

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

Required to find: Probability of getting a

(i) red ball

(ii) white ball

Total number of balls 3 + 5 = 8

(i) Total number red balls are 3

We know that, Probability = Number of favourable outcomes/ Total number of outcomes

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

(ii) Total number of black ball are 5

We know that, Probability = Number of favourable outcomes/ Total number of outcomes

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