Answer 2

Given,

Preethi was born between August 26th and 30th (26th and 30th excluding)

To Find,

The probability of Preethi being born on a Monday =?

Solution,

Preethi was born between August 26th and 30th which means she could be born on the 27th, 28th, and 29th of August as 26th and 30th are excluded.

The possible cases for these 3 days: (Sunday, Monday, Tuesday)(Monday, Tuesday, Wednesday),(Friday, Saturday, Sunday),(Thursday, Friday, Saturday,),(Wednesday, Thursday, Friday),(Saturday, Sunday, Monday),(Tuesday, Wednesday, Thursday)

The number of total cases = 7

The number of cases with Monday is one of 3 days = 3

The probability of Preethi being born on a Monday = 3 / 7

Hence, the probability of Preethi being born on a Monday is 3/7.
