Question

what is the probability that a leap year, selected at random will contain 53 thrusday ?

Answer 1

Hey... I think this can be ur answer dear!!

A leap year has 52 weeks and 2 days...

These 2 days can be:-

1) Sunday and Monday

2)Monday and Tuesday

3)Tuesday and Wednesday

4)Wednesday and Thursday

5)Thursday and Friday

6)Friday and Saturday

7)Saturday and Sunday

Therefore, n(S) =7
n(E) =2

SO the probability that there are 53 Thursdays in leap year is = n(E)/n(s) =2/7

Hope it helps you dear ☺️☺️
