I am stuck on this probability question:

Any suggestions of where to start would be great!! Thanks!

Given 20 people, what is the probability that among the 12 months

in the year there are 2 months containing exactly 4 birthdays each and there are 6

months containing exactly 2 birthdays each? Assume that each month is equally

likely and birthdays are independent.
