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 :
Now, the probability that both children are boys=
The chance both children are boys = 0.263169
Here, 1 / (9y - 7) = 2 / 4y
4y = 2(9y - 7)
4y = 18y - 14
18y - 4y = 14
14y = 14
y = 14/14
y = 1
In short, Your Answer would be 1
Hope this helps!
