Your Answer
C
1
Your Answer
D
515

Solution

The correct option is B 715
Number of black balls = 5
Number of red balls = 7
Number of white balls = 3
Total number of balls in the bag = 5 + 7 + 3 = 15
As, drawing a ball from the bag are equally likely events, total number of outcomes = 15
Let E1 represents event of drawing a red ball
P(E1)=Number of favourable outcomesTotal number of outcomes=715
