In a study, 36% of adults questioned reported that their health was excellent. a researcher wishes to study the health of people living close to a nuclear power plant. among adults randomly selected from this area, only 3 reported that their health was excellent. find the probability that when adults are randomly selected, 3 or fewer are in excellent health. round to three decimal places.

0.3907

Step-by-step explanation:

We are given that 36% of adults questioned reported that their health was excellent.

Probability of good health = 0.36

Among 11 adults randomly selected from this area, only 3 reported that their health was excellent.

Now we are supposed to find the probability that when 11 adults are randomly selected, 3 or fewer are in excellent health.

i.e.

Formula :

p is the probability of success i.e. p = 0.36

q = probability of failure = 1- 0.36 = 0.64

n = 11

So,

Hence  the probability that when 11 adults are randomly selected, 3 or fewer are in excellent health is 0.3907

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
