Question

A bag contains 18 balls out of which x balls are red.

I) ifone ball is drawn at random from the bag, what is the probability that it is not red?

ii) if 2 more red balls are put in the bag. the probability of drawing a red ball will be 8/9
times the probability of drawing a red ball in the first case. Find the value of x​

Answer 1

Answer:

No. of red balls = x

No. balls that are not red = 18-x

i) Probability = (18-x)/18

ii) New no. of red balls = x+2

Given,

(x+2)/20= 8/9 (x/18)
