Question

the probability that a leap year will have 53 Fridays or 53 Saturday​

Answer 1

Answer:

leap year will have 53 friday or 53 saturday

Answer 2

Answer:

4/7

Step-by-step explanation:

we know in a leap year there are 366 days

Also, there are seven days in a week

so,

$366 \: days = 52 \: week \times 7 + 2 \: days$

now , for 52 weeks no. all days will be same

but 2 days are extra

so,

sample space for that 2 days can be

sunday and Monday ; monday and Tuesday ;

Tuesday and Wednesday ; Wednesday and

Thursday ; Thursday and Friday ; Friday and Saturday ; Saturday and Sunday

therefore no. of events on sample space is =7

no. of events having Friday and Sunday

are = 4

therefore probability is

$\frac{number \: of \: favourable \: event}{number \: of \: total \: event}$

i.e.

$\frac{4}{7}$
