Question

the probability that leap year selected at random contain 53 sundays?
​

Answer 1

Answer:

Step-by-step explanation:

In a leap year there are 366 days = 52 weeks + 2 days

Those 2  days can be (sun , mon);(mon ,tue);(tue ,wed);(wed ,thu);(thu ,fri);(fri ,sat) or (sat ,sun)

So one of the 2 days can be a sunday only in 2 cases ,i.e. , (sun , mon) or (sat ,sun) .

P(having 53 sundays in a leap year ) = 2/7
