In a family having three children, there may be no girl, one girl, two girls or three girls. So, the probability of each is 1/4 . Is this correct? Justify your answer

Solution:

Consider B as boys and G as girls

So the outcomes are

BBB, GGG, BBG, BGB, GBB, GGB, GBG, BGG

Probability of 3 girls = 1/8

Probability of 0 girls = 1/8

Probability of 2 girls = 3/8

Probability of 1 girl = 3/8

Therefore, the statement is not correct.

✦ Try This: An event is very unlikely to happen. Its probability is closest to a. 0.0003, b. 0.003, c. 0.03, d. 0.3

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

The probability of an event which is unlikely to happen is close to zero i.e. 0.0003

Therefore, its probability is closest to 0.0003.
