Answer:$9,000
Step-by-step explanation:
150,000 x 0.06
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}](https://tex.z-dn.net/?f=P%28X%3Dx%29%3D%5EnC_xp%5Ex%281-p%29%5E%7Bn-x%7D)
Now, the probability that both children are boys= ![P(X=2)=^2C_2(0.513)^2(1-0.513)^0](https://tex.z-dn.net/?f=P%28X%3D2%29%3D%5E2C_2%280.513%29%5E2%281-0.513%29%5E0)
![=(1)(0.513)^2(1)\\\\=0.263169](https://tex.z-dn.net/?f=%3D%281%29%280.513%29%5E2%281%29%5C%5C%5C%5C%3D0.263169)
The chance both children are boys = 0.263169
