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?
Hint: It is not 1/2 as you would first think.

- The following are possible combinations of two children that form a sample space in any earthly family:
Girl - Girl
Girl - Boy
Boy - Girl
Boy - Boy
Since we know one of the children is a girl, we will drop the Boy-Boy possibility from the sample space.
This leaves only three possibilities, one of which is two girls. Hence the probability is 1/3 - 8 years agoHelpfull: Yes(33) No(5)
- can someone explain the answer of question???

- 1/2*1/2=1/4

- here one of the kid is girl. so the other should be boy. so the probability of getting girl is 0.
- 8 years agoHelpfull: Yes(1) No(2)
- They said that one of the child is girl..so definitely the other child will be either girl or boy..the probability for getting a girl is only one chance..so the answer will be 1.

THEY said the probability of each gender is 1/2
so
G G ------- 1/2*1/2=1/4
G B ---------1/2*1/2=1/4
B G -------- 1/2*1/2=1/4
SO we add 1/4+1/4+1/4 ==3/4 - 4 years agoHelpfull: Yes(1) No(0)
- 1/2*1/2=1/4
- 8 years agoHelpfull: Yes(0) No(3)
- please explain the above problem
- 8 years agoHelpfull: Yes(0) No(0)
- answer is 1/4

- one of the children is 1/2.(In terms of 6 months)
other children is also 1/2(In terms oh 6 months)
=1/2+1/2=1.
therfore other kid is 1/2. - 6 years agoHelpfull: Yes(0) No(3)
- Each gender probability. 1/2 okey
Now couple one of them girl baby 1/2
Read question carefully assume okey
No chance for couple another girl so probality answer is zero - 6 years agoHelpfull: Yes(0) No(1)
