Question

The probability of the month of February of non – leap year having 5 Sundays is ______
(A) 1/7 (B) 2/7 (C) 3/7 (D) 0​

Answer 1

Answer :-

In non - leap year, February has 28 days.

So, let's calculate the weeks and the number of days other than the total weeks -

→ 28 / 7 = 4 weeks and 0 extra days.

As there are 4 weeks it is confirmed that February has 4 Sundays.

Now, we have to find the probability of having one more sunday.

As February has exactly 4 week, there is no day left and so there can be no other day.

So, February can have only 4 sundays.

As the asked event is not possible, probability will be 0.

The probability of the month of February of non – leap year having 5 Sundays is 0.

Answer 2

Answer:

Now, this extra day could be any of the 7 days of sunday, monday, tuesday, wednesday, thursday, friday and saturday. and probability of getting sunday from these 7 days= 1/7. So, the probability of 5 sundays in february of a leap year is 1/7.
