Question

Find the probability that the birthday of a child is on a Saturday or Sunday

Answer 1

Answer:

Step-by-step explanation:

1 months=4+4

=8

So..

Total outcomes= 12×8

= 96

P= 8/96

= 1/12

Answer 2

Answer:

The probability that the birthday of a child is Saturday or Sunday = $\frac{2}{7}$

Step-by-step explanation:

We know that the probability of occurring an event = $\frac{No \ of \ possible \ outcomes}{ Total \ no\ of \ outcomes}$

Required to find,

The probability that the birthday of a child is Saturday or Sunday.

Total number of outcomes = Birthday of the child can be any day of week = No. days in a week = 7

∴ Total number of outcomes = 7

No. of possible outcomes = birthday of the child is either Saturday or Sunday

= 2

∴ Number of possible outcomes  = 2

Hence, the required probability   = $\frac{No \ of \ possible \ outcomes}{ Total \ no\ of \ outcomes}$ = $\frac{2}{7}$

∴The probability that the birthday of a child is Saturday or Sunday = $\frac{2}{7}$
