Answer:

GIVEN : Number of red balls = 7

Number of white balls = 3

Number of black balls = 5

Total number of balls in a bag = 7 + 3 + 5 = 15

Total number of outcomes = 15

(i) Let E1 = Event  of selecting that a  ball drawn is red

Number of red balls = 7

Number of outcome favourable to E = 7

Probability (E1) = Number of favourable outcomes / Total number of outcomes

P(E1) = 7/15
