# A bag contains 3 red balls, 5 black balls and 4 white balls. A ball is drawn at random from the bag. What is the probability that the ball drawn is :(i) White?(ii) red?(iii) black?(iv) not red?

(i) White?

Total numbers of red balls = 3

Number of black balls = 5

Number of white balls = 4

Total number of balls = 3 + 5 + 4 = 12

Probability of getting a white ball is = (ii) red?

Total numbers of red balls = 3

Number of black balls = 5

Number of white balls = 4

Total number of balls = 3 + 5 + 4 = 12

Probability of getting a red ball is = (iii) black?

Total numbers of red balls = 3

Number of black balls = 5

Number of white balls = 4

Total number of balls = 3 + 5 + 4 = 12

Probability of getting a black ball is = (iv) not red?

Total numbers of red balls = 3

Number of black balls = 5

Number of white balls = 4

Total number of Non red balls = 5 + 4 = 9

Probability of getting a non red ball is = Rate this question :
