The television show Lost has been successful for many years. That show recently had a share of 24, meaning that among the TV sets in use, 24% were tuned to Lost. Assume that an advertiser wants to verify that 24% 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 Lost broadcast. Find the probability that none of the households are tuned to Lost. P(none) = Find the probability that at least one household is tuned to Lost. P(at least one) = Find the probability that at most one household is tuned to Lost. P(at most one) = If at most one household is tuned to Lost, does it appear that the 24% share value is wrong? (Hint: Is the occurrence of at most one household tuned to Lost unusual?) yes, it is wrong no, it is not wrong
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Find the probability that none of the households are tuned to Lost.
P(none) =
Find the probability that at least one household is tuned to Lost.
P(at least one) =
Find the probability that at most one household is tuned to Lost.
P(at most one) =
If at most one household is tuned to Lost, does it appear that the 24% share value is wrong? (Hint: Is the occurrence of at most one household tuned to Lost unusual?)
- yes, it is wrong
- no, it is not wrong
