उत्तर
The probability that the month of April has exactly 5 Mondays is `underlinebb(2/7)`.
Explanation:
April has 30 days or 4 weeks and 2 extra days. Monday occurs 5 times when the two extra days include Monday.
The two extra days include Monday in 2 of the 7 possible weekday pairs; hence the probability is \[\frac{2}{7}\].
