Question

find the probability of getting 53 Fridays in a leap year​

Answer 1

Step-by-step explanation:

A leap year has 52 complete weeks plus 2 days. Hence if the leap year begins on a Sunday, it will have 53 Sundays and Mondays and 52 other days of the week. Thus a leap year will have 53 Fridays if the year begins on a Thursday or Friday. The probability that a leap year begins on any day of the year is the same = 1/7.

Answer 2

given

366 days

53 Fridays

solution

n(s)=366

n(a)=53

P(a)=366/53

=7.......or 6.90
