Question

A bag contains 3 red balls 5 black balls and 4 blue balls. A ball drawn at random from the bag .what is the probability that (1) it is a red ball? (2)it is not blue ball?

Answer 1

Step-by-step explanation:

There are 3red balls

Now,Total possible outcomes=12

No. of favourable outcomes=3

P(getting a red ball)=3/12=1/4

(2) There are 8 balls which are not blue.

Now,Total possible outcomes=12

No. of favourable outcomes=8

P(not getting a blue ball)=8/12=2/3
