Question

Find the probability of having 5 Sundays in the month of February in leap year 2004.

• A. 2/7
• B. 0
• C. 1/7
• D. 1

Answer 1

The correct option is C 1/7

Let $A$ be the event that there are $5$ Sundays in February $2004$.
The number of days in February' $2004=29$
That is, $4$ weeks and $1$ more day
There are $4$ Sundays in $4$ weeks.
However, the last day can be any day in the last week
So, the probability of the event $A=\frac{1}{7}$
So, the correct option is (C).
