The television show Lett3rs has been successful for many years. That show recently had a share of 16, which means, that among the TV sets in use, 16% were tuned to Lett3rs. An advertiser wants to verify that
16% share value by conducting its own survey, and a pilot survey begins with 10 households have TV sets in
use at the time of a Lett3rs broadcast.
Find the probability that none of the households are tuned to Lett3rs.
P(none) -
Find the probability
that at least one household is tuned to Lett3rs.
P(at least one) -
Find the probability that at most one household is tuned to Lett3rs.
Plat most one) -
If at most one household is tuned to Lett3rs, does it appear that the 16% share value is wrong? (Hint: Is the
occurrence of at most one household tuned to Lett3rs unusual?)
yes, it is wrong
O no, it is not wrong
