Problem 4.28: people with type o-negative blood are
universaldonors. that is, any patient can receive a transfusion
ofo-negative blood. only 7% of the american population
haveo-negative blood. if 10 people appear at random to give blood,
whatis the probability that at least 1 of them is a
universaldonor?

0.516

Step-by-step explanation:

Binomial probability distribution formula to find the probability of getting success in x trial:-

, where n is the number of trials , p is the probability of getting success in each trial.

Given :  People with type O-negative blood are  universal donors.

The proportion of  the American population  have O-negative blood =0.07

For n=10, the probability that at least 1 of them is a  O-negative blood :-

Hence, the probability that at least 1 of them is a  universal donor = 0.516

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic

the car was traveling 40 mph before it started skidding. ( 2 points ) 17. was the driver were her brakes working at 75% efficiency or better? ( 2 points ) yes 29.
