Question

Suppose there were 4,065,014 births in a given year. Of those births 2,081,287 were boys and 1,983,727 were girls. What is the probability that both children will be boys?

Answer 1

Answer:

The required probability is $\simeq 0.26214$

Step-by-step explanation:

There were 4,065,014  births in a given year and of those births 2,081,287 were boys and 1.983,727  were girls.

So, P(both children will be boys) = $\frac {^{2081287}{C}_2}{^{4065014}{C}_{2}}$

$\simeq 0.26214$
