The probability of having 5 mondays is 0
February has 5 mondays only in a leap year.
In a non- leap year february has only 4 mondays
Therefore the probability is 0

In a non leap year no.of days in february = 28 days
n(S) = 28
Let E be the event of getting 5 mondays
n(E) = 0
P(E) = n(E)/n(S)
= 0/28 = 0
thanks
