The Anderson family has 3 kids 3 boys and 0 girls suppose that for each birth the probability of a boy birthday is 1/2 and the probability of a girl birth is also 1/2 what is the fractional probility of having 3 boys and 0 girls ina family first 3 births

Fractional probability of having 3 boys and 0 girls in a family for first 3 births is .

Step-by-step explanation:

Let A be the event of birth of a boy.

Let B be the event of birth of a girl.

Probability of birth of a boy, P(A)

Probability of birth of a girl, P(B)

We have to find the probability of birth of 3 boys i.e. event A occurring 3 times in a succession. It is independent events i.e. do not have any dependency on occurrence of any event.

So, Required probability can be calculated just by multiplying P(A) for 3 times.

i.e.

So, the probability of having 3 boys and 0 girls in the family is .

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
