tipli and pikli are a married couple (dont ask me who he is and who she is)
They have two children, one of the child is a boy. Assume safely that the probability of each gender is 1/2.
What is the probability that the other child is also a boy?
Hint: It is not 1/2 as you would first think. Choose the most appropriate option:
A) 1/9  B) 1/3  C) 3/5  D) 1/8  E) 1/4
B   1/3   This is a famous question in understanding conditional probability, which simply means that given some information you might be able to get a better estimate.   The following are possible combinations of two children that form a sample space in any earthly family:   Boy - Girl   Girl - Boy   Boy - Boy   Girl - Girl   Since we know one of the children is a boy, we will drop the girl-girl possibility from the sample space.   This leaves only three possibilities, one of which is two boys. Hence the probability is 1/3
