Question

The probability that a leap year selected at random will contain 53 wednesday

Answer 1

Dear student, greetings from this side.

A leap year has 366 days which makes 52 COMPLETE WEEKS and 2 extra days.

These two days may be

1) Monday and Tuesday

2)Tuesday and WEDNESDAY

3)WEDNESDAY and Thursday

4)Thursday and Friday

5)Friday and Saturday

6)Saturday and Sunday

7)Sunday and Monday

Hence total cases = 7

Favourable cases = 2 (Tuesday and WEDNESDAY ,WEDNESDAY and Thursday)

Hence required probability = 2/7

Hope the answer might have cleared all your doubt regarding the question.
