Question

A bag contains 10 red balls, 15 green balls and 25 blue balls. A ball is drawn at random from the bag. Find the probability that the ball drawn is not in red colour Full Marks : 1 (a) 0.5
 (b) 0.6
 (c) 0.7
 (d) 0.8​

Answer 1

Answer:

(d) 0.8

Step-by-step explanation:

Total No. of balls in the bag = 50

No. of red balls = 10

No. of non-red balls = 50-10

=40

P(E)= No. of favourable outcomes / Total No. of outcomes

Probability of getting a non-red ball

= No. of non-red balls / Total No. of balls

=40/50

=4/5

=0.8

Hence, (d)0.8 is the correct option.
