Question

A bag contains som balls of which are white, 2x are black and 3x are red. A bal is selewed at random.
Find the probability that it is (1) not red, (u) white.
​

Answer 1

total balls is 6x

1)p(not red)=3x/6x=1/2 [ favourable outcomes=x+2x

2)p(white)=x/6x=1/6 [ favourable outcomes=x]

Answer 2

Answer:

total no.of balls = x+2x+3x=6x

no.of balls not red =x+2x=3x

probability of not getting red balls=3x/6x=1/2

probability of getting white=x/6x=1/6
