Question

what is probability of getting 5 saturdays and 5 sundays in the month of april​

Answer 1

Answer:

We know that

November has 30 days, which means 4 weeks and 2 days.

Now, 4 weeks will contain 4 Sunday.

The remaining 2 days may be :

1. Sunday and Monday

2. Monday and Tuesday

3. Tuesday and Wednesday

4. Wednesday and Thursday

5. Thursday and Friday

6. Friday and Saturday

7. Saturday and Sunday

Total number of possible outcomes = 7

Now, favourable outcomes are : Sunday and Monday, Saturday and Sunday

Number of favourable outcomes = 2

Required probability (P)= Number of favourable outcomes /Total number of possible outcomes

P = 2/7

Answer 2

Answer:

That means that every April (and any other 30-day month; there are 4 every year) there are 2 consecutive days of the week of which there are 5 that month. If those 2 days are Saturday and Sunday, or Sunday and Monday, there will be 5 Sundays that month, otherwise not. These happen approximately 2/7 of the time
