Answer 1

SOLUTION

TO CHOOSE THE CORRECT OPTION

The probability of getting 53 Sundays in a leap year

$\displaystyle \sf{ 1. \: \: \frac{1}{7} }$

$\displaystyle \sf{ 2. \: \: \frac{3}{7} }$

$\displaystyle \sf{ 3. \: \: \frac{2}{7} }$

4. None of these

EVALUATION

Leap year = 366 days

366 days = 52 weeks 2 days

Now 52 weeks contains 52 Sundays

2 days is one of the below

( Sunday, Monday), ( Monday, Tuesday), (Tuesday, Wednesday), ( Wednesday, Thursday), ( Thursday, Friday), ( Friday, Saturday ), (Saturday, Sunday)

So the total number of possible outcomes = 7

Let A be the event that of getting 53 Sundays in a leap year

So the total event points for the event A is (Saturday, Sunday), ( Sunday , Monday )

So the total number of possible outcomes for the event A is 2

Hence the required probability

= P(A)

$\displaystyle \sf{ = \frac{2}{7} }$

FINAL ANSWER

Hence the correct option is

$\displaystyle \sf{ 3. \: \: \frac{2}{7} }$
