Answer 1

(i) Red Total numbers of red balls = 3 Number of black balls = 5 Total number of balls = 3 + 5 = 8 Probability of getting a red ball is = Total number of red balls/Total number of balls = 3/8 ∴ Probability of getting a red ball is 3/8 (ii) Black Total numbers of red balls = 3 Number of black balls = 5 Total number of balls = 3 + 5 = 8 Probability of getting a black ball is = Total number of black balls/Total number of balls = 5/8 ∴ Probability of getting a black ball is 5/8
