The probability that the birthdays of five persons chosen at random will fall in twelve different calender months is zero. You would need at least twelve persons to have a non zero probability.
If the probability is 5/12 then that is an acceptable answer in itself however it is also the same thing as 5 divided by twelve or .4167
The probability is 7/36.
The probability to get a 12, with two dice, is 1/36.

Ten to twelve eggs.
