Question

the probability of a month of february in a non-leap year having 5 monday is ............... explain
a. 1/5 b.2/7 c.1/7 d.0

Answer 1

answer is zero,
because in non -leap year, february is of 28 days and every single day comes only 4 times.

Answer 2

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
