Question

32.A month is selected at random in a non leap year. Calculate the
probability that
a. The month has even number of days
b. The month has odd number of days.​

Answer 1

Step-by-step explanation:

A non-leap year has 365 days i.e. 52 weeks and 1 odd days.

So, there are 52 Sundays always.

But the odd day can be Sunday, Monday, Tuesday, Wednesday, Thursday, Friday or Saturday.

So, there are 7 possibilities for odd day and out of which one is favourable.

So, the probability of getting Sunday on last week is 1/7

Thus, the probability of getting 53 Sundays in a non-leap year is 1/7
