Step-by-step explanation:

A person can have birthday in any of the 12 months of the year.Another person can also have his/her birthday in any of the 12 months.Now,the total number of possible combinations is 12*12 , which equals 144.

This set of all possible combinations contains 12 pairs of identical months {for example(Jan,Jan)},which are our favorable outcomes.

Thus the probability =

(Number of favorable outcomes)/(Number of events in sample space)=

12/(12*12)=1/12
