A person with type AB blood can donate red blood cells to people with the same blood type. About 12% of the US population has type AB blood. University High held
a blood drive where 50 students donated blood.

Part A: What is the probability that exactly 8 of the students had type AB blood? (5 points)

Part B: What is the probability that at least 8 of the students had type AB blood? (5 points)

5

step-by-step explanation:

a

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
