Detailed Solution

No. of red balls = 5 and No. of black balls = 3

The total number of balls = 5 + 3 = 8

We know that

P(E) = (Number of favorable outcomes/ Total number of outcomes)

(i) Probability of drawing red balls

P (red balls) = (no. of red balls/total no. of balls)

= 3/8

(ii) Probability of drawing black balls

P (black balls) = (no. of black balls/total no. of balls)

= 5/8
