The television showLaw & Disorder has been successful for many years. That show recently had a share of 18, meaning that among the TV sets in use, 18% were tuned toLaw & Disorder. Assume that an advertiser wants to verify that 18% share value by conducting its own survey, and a pilot survey begins with 13 households have TV sets in use at the time of aLaw & Disorder broadcast.


Find the probability that none of the households are tuned toLaw & Disorder.

P(none) =


Find the probability that at least one household is tuned toLaw & Disorder.

P(at least one) =


Find the probability that at most one household is tuned toLaw & Disorder.

P(at most one) =


If at most one household is tuned toLaw & Disorder, does it appear that the 18% share value is wrong? (Hint: Is the occurrence of at most one household tuned toLaw & Disorder unusual?)
