Question

A bag consists 6 white, 5 black and 4
yellow balls. Find the chance of
getting either a black or yellow ball.​

Answer 1

Answer:

total number of outcomes =6+5+4=15

probability of getting both black or yellow ball= 9/15

Answer 2

Answer:

White balls = 6

Black balls = 5

Yellow balls= 4

Total balls = 15

P(black ball) = favourable outcome / total outcome = 5/15 = 1/3

P(yellow ball) = 4/15
