Question

What are the chance of occurrence of three consecutive boy child to couple:

• A. $1/8$
• B. $2/8$
• C. $2/6$
• D. $3/8$

Answer 1

The correct option is A $1/8$

Having a boy or a girl is an independent event and does not depend on whether the previous event is same or different. The probability of having a boy child in first attempt is (1/2), as it is in the second and third attempt. Thus the total chance of occurence of three consecutive boy child to a couple is 0.5 X 0.5 X 0.5 = 1/8.

So the correct option is '1/8'.
