At least two girls means either 2, 3 ... or 8 girls.
Using the binomial law, we can write the probability in the form:
B(2,0.5)+B(3,05)+...+B(8,0.5)=
Continue simplifying:
Answer:
y = 7/2x+5
Step-by-step explanation:
To find the slope we need two points
(-2,-2) and (0,5)
We can find the slope from the formula
m = (y2-y1)/(x2-x1)
m = (5--2)/(0--2)
m = (5+2)/(0+2)
m = 7/2
The slope is 7/2
The y intercept, or where it crosses the y axis, is 5
Using the slope intercept formula for a line
y= mx+b
y = 7/2x+5

It is helpful to find a unit rate first. If you find a unit rate first, then it will be easier to compare
