The rhythm method of contraception is rated as 60% effective. find the probability that it will be effective in each of five (5 out of 5) separate trials.

P(5R) = 0.60^5

P(5R) = 0.07776 = 0.078

Therefore the probability that it will be effective in each of five (5 out of 5) separate trials is 0.078

Step-by-step explanation:

Given;

The probability that the rhythm method of contraception is effective once is P(R) = 0.60

The probability that it will be effective n times is;

P(nR) = 0.60^n

For this case n= 5

P(5R) = 0.60^5

P(5R) = 0.07776

P(5R) = 0.078

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
