The expected number of female children in a family with three children is 1.5.
The correct option is B.
We have to determine
What is the expected number of female children in a family with three children?
<h3>Probability;</h3>
Probability is defined as the sum of all observations and the number of observations.
The expected value of female children= Probability of female children x Total number of children.
A child can be male or female, so there are 2 combinations, the favorable outcome is female.
The probability of female children = 1/2.
Therefore,
The expected number of female children in a family with three children is;
![= \dfrac{1}{2}\times 3\\\\=1.5](https://tex.z-dn.net/?f=%3D%20%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%203%5C%5C%5C%5C%3D1.5)
Hence, The expected number of female children in a family with three children is 1.5.

Answer:
Slope: 5
Point: ![(3,13)](https://tex.z-dn.net/?f=%283%2C13%29)
Step-by-step explanation:
We have been given that a line's equation is point-slope form
. We are asked to find the slope of the line and a point on this line that is apparent from the given equation.
We know that point-slope form of an equation is in form
, where
m = Slope of line,
= Coordinates of points the is on the line.
Upon looking at our given equation, we can see that
, therefore, the slope of the line is 5.
We can also see that
, therefore, point
is one the given line that is apparent from the given equation.
Answer:
the first option
Step-by-step explanation:
i know there's a rule to all of this but it's been a while since i've done this kind of math.
if you plug in the zeros to the equation, they solve
(-2, 0) --> (-2-2)(-2+1)(-2+2) = 0
(-1, 0) --> (-1-2)(-1+1)(-1+2) = 0
(2, 0) --> (2-2)(2+1)(2+2) = 0
