Question

A box contains 200 red balls, 150 black balls and 100 yellow balls. If a ball is drawn randomly from the box, then find the probability that it will be a

(a) yellow ball

(b) neither yellow nor black ball

(c) not a red ball

Answer 1

Number red balls =200
Number of black balls =150
Number of yellow balls =100
Total number of balls =450
Probability of drawing a yellow ball =100/450=2/9
Probability of drawing neither yellow nor black ball =probability of drawing drawing red ball=200/450=4/9
Probability of drawing ball which is not red=probability of drawing yellow or black =250/450=5/9

Answer 2

Answer:

Step-by-step explanation

No. of red balls=200

No. of black balls=150

No. of yellow balls=100

Total no. of balls=450 balls.

A) P of (yellow ball) =100/450 = 2/9

B) P of (neither yellow nor black ball) = 450-(150+100)/450 = 200/450 =4/9

C) P of (not red ball) = 450-200/450 = 5/9..

I Hope this helps you

Thank you..
