To find the probabilities associated with the students that do not buy compact discs.
Explanation of Solution
Given:
A survey that found that
Calculation:
The probability of
Here p represents the probability of success and q represents the probability of failure.
Since
While the remaining 9% buy them, so,
Substitute in the above formula to find the probability that none of the
Thus, the probability that none of the 8 random students do not buy compact discs is.
Substitute in the above formula to find the probability that exactly 1 of the 8 random students surveyed do not buy compact discs,
Substitute in the above formula to find the probability that exactly 2 of the 8 random students surveyed do not buy compact discs,
......
Thus, the probability that all 8 random students surveyed do not buy compact discs is.
To find the probability that at least
Answer to Problem 17STP
Explanation of Solution
Given:
A survey that found that
Calculation:
The number of students out of
From part a, it is clear that,
So, the probability that at least
Thus, the probability that at least
To find the probabilities associated with the students that do not buy compact discs.
Answer to Problem 17STP
Explanation of Solution
Given:
A survey that found that
Calculation:
In general, the mean, of any binomial distribution is,
Here n is the number of trials and p is the probability of success.
For the above situation, it is clear that
Thus, the number of students expected who do not buy compact discs is
