A Harris Interactive survey for Inter Continental Hotels & Resorts asked respondents, “When
traveling internationally, do you generally venture out on your own to experience culture, or stick
with your tour group and itineraries?” The survey found that 23% of the respondents stick with
their tour group (USA Today, January 21, 2004).
A. In a sample of six international travelers, what is the probability that two will stick with their
tour group?
B. In a sample of six international travelers, what is the probability that at least two will stick
with their tour group?
C. In a sample of 10 international travelers, what is the probability that none will stick with the
tour group?
@Bezi,
Before trying to tackle A and B, do you know how to do C? Hint: if the probability that someone will stick with the group is 23%, the probability they will not is 77%.
