Acertain tv show recently had a share of 65, meaning that among the tv sets inuse, 65% were tuned to that show. assume that an advertiser wants to verify that 65% share value by conducting its own survey, and a pilot survey begins with 10 households having tv sets in use at the time of the tv show broadcast.

complete parts (a) through (d) below.

a. find the probability that all the households are tuned to the tv show is
b. find the probability that exactly 11 households are tuned to the tv show
c. find the probability that at least 11 households are tuned to the tv show
d. if at least 11 households are tuned to the tv show, does it appear that the 65% share value is wrong? why or why not?
