Answer 2

Answer:

Hey here is you answer

Step-by-step explanation:

No. of days in a leap =366

(  7 l  366   =52.28)

So, there will be 52 weeks and 2 days

So, every leap year has 52 Sundays

Now, the probability depends on remaining 2 days

The possible pairing of days are  

Sunday-Monday

Monday-Tuesday

Tuesday-Wednesday

Wednesday-Thursday

Thursday-Friday

Friday-Saturday

Saturday-Sunday

There are total 7 pairs and out of 7 pairs, only 2 pairs have Sunday. The remaining 5 pairs does not include Sunday

Thus, the probability of not getting Sunday in the last 2 days is   = 7  l5  

Therefore, the probability of only 52 Sundays in a Leap year is   = 7  l 5​  .
