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.
1 answer:
Answer:
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
