find the probability of having a. 5 monday in the month of january i)in a leap year ii)in a nonLeap year. b. 5 monday in the month of february i)in a leap year ii)in a nonLeap year.
The probability that a given day is a Monday is 1/7. Hence, the required probability is 1/7.
In a non-leap year, February has 28 days. So each day occurs exactly 4 times. So the probability of having 5 Mondays is Zero.
