Question 663918: The television show Found has been successful for many years. That show recently had a share of 27, meaning that among the TV sets in use, 27% were tuned to Found. Assume that an advertiser wants to verify that 27% share value by conducting its own survey, and a pilot survey begins with 15 households have TV sets in use at the time of a Found broadcast.
Find the probability that none of the households are tuned to Found.
P(none) =
Find the probability that at least one household is tuned to Found.
P(at least one) =
Find the probability that at most one household is tuned to Found.
P(at most one) =
Just curious: You said, and I quote: "...to be completely honest." To me, that means that previous to having made that statement, you were less than completely honest. So what is it about the earlier part of your post that is dishonest? Please continue to be completly honest or at least warn me when you begin to dissemble or otherwise communicate falsehoods.
The probability of successes in trials where is the probability of success on any given trial is given by:
Where is the number of combinations of things taken at a time and is calculated by
The probability of none is then:
and the probability of one is:
