Answer: 0.263169

Step-by-step explanation:

Since for every child there is two outcomes (either a boy or a girl), so it is a binomial distribution.

Let x = Number of boys

Given: probability that a child is a boy: p= 0.513

Binomial distribution formula : $P(X=x)=^nC_xp^x(1-p)^{n-x}$

Now, the probability that both children are boys= $P(X=2)=^2C_2(0.513)^2(1-0.513)^0$

$=(1)(0.513)^2(1)\\\\=0.263169$

The chance both children are boys = 0.263169
