Question

Aniket and kumari are a married couple (dont ask me who he is and who she is)! They have two kids, one of them is a girl. Assume safely that the probability of each gender is 1/2.
What is the probability that the other kid is also a girl?

Answer 1

Let,

G= girl

B=boy

As we know that one of the child is girl so, the conditions, which may come:

G G

G B

B G

Total outcome = 3

Favourable outcome = 1

∴ Probability = 1/3

Answer 2

Answer:

The probability is $1/3$.

Step-by-step explanation:

Aniket and Kumari are a married couple.

They have two kids, one of them is a girl.

It is given that probability of each gender is $1/2$

We need to determine the probability that other kid is also a girl.

Assuming G= girl and B=boy

Since one of the child is girl so, the conditions, which may arise may be:

GG, GB, BG

Total outcomes are $3$

Favorable outcome is GG $(1)$

Probability is $1/3$.
