Question

A ball has 10identical balls of different colours I. e. 4red;4green;2blue.A ball is drawn from the bag without looking the colour. What is the probability of getting a blue ball?

Answer 1

Answer:

1/5

Step-by-step explanation:

Total number of balls = 10

So, the total number of possible outcomes = 10

Number of blue balls = 2

The number of ways a blue ball could be picked = 2

Probability of getting a blue ball = The number of ways blue balls could be picked / Total number of possible outcomes

                                                   = 2/10

                                                   = 1/5

Therefore, the required probability = 1/5
