SOLUTION
No. of red balls = 3
No. of black balls = 5
Total no. of balls = 5+3 = 8
(i) Probability of drawing red balls = No. of red balls/Total no. of balls = 3/8
(ii) Probability of drawing black balls = No. of black balls/Total no. of balls = 5/8
No. of red balls = 3
No. of black balls = 5
Total no. of balls = 5+3 = 8
(i) Probability of drawing red balls = No. of red balls/Total no. of balls = 3/8
(ii) Probability of drawing black balls = No. of black balls/Total no. of balls = 5/8
