Answer» Sol: A non-leap year has 365 days A year has 52 weeks. Hence there will be 52 Sundays for sure. 52 weeks = 52 x 7 = 364 days . 365– 364 = 1day extra. In a non-leap year there will be 52 Sundays and 1day will be left. This 1 day can beSunday, Monday,Tuesday, Wednesday, Thursday,friday, saturday, Sunday. Of these total 7 outcomes, the favourable outcomes are 1. Hence the probability of getting 53 sundays = 1 / 7. 2)∴ probability of getting 52 sundays = 1 - 1/ 7 = 6 / 7. sir question solve ho gaya

Answer»

Sol:

A non-leap year has 365 days

A year has 52 weeks. Hence there will be 52 Sundays for sure.

52 weeks = 52 x 7 = 364 days .

365– 364 = 1day extra.

In a non-leap year there will be 52 Sundays and 1day will be left.

This 1 day can beSunday, Monday,Tuesday, Wednesday, Thursday,friday, saturday, Sunday.

Of these total 7 outcomes, the favourable outcomes are 1.

Hence the probability of getting 53 sundays = 1 / 7.

2)∴ probability of getting 52 sundays = 1 - 1/ 7 = 6 / 7.
