Amay 2000 gallup poll found that 38% of the people in a random sample of 1,012 adult americans said that they
believe in ghosts. suppose that three adults will be randomly selected with replacement from the group that responded
to this poll, and the number of adults (out of the three) who believe in ghosts will be observed.
10. develop a discrete probability distribution for the number of adults in the sample who believe in ghosts
11. calculate the probability that at least one adult, but at most two adults, in the sample believes in ghosts. interpret
this probability in context.
12. out of the three randomly selected adults, how many would you expect to believe in ghosts? interpret this
expected value in context.
