The makers of a diet cola claim that its taste is indistinguishable from the full-

prepared small samples of each type of soda in identical cups. Then she had
15 volunteers taste each cola in a random order to try to identify which was
the diet cola and which was the regular cola. If we assume that the volunteers
couldn't tell the difference, then each one was guessing with a % chance of
being correct. Let Y = the number volunteers who correctly identify the colas.

The probability that a u.s. resident has traveled to canada is 0.18 and to mexico is 0.09. a. if traveling to canada and traveling to mexico are independent events, what is the probability that a randomly-selected person has traveled to both? (page 109 in the book may ) b. it turns out that only 4% of u.s. residents have traveled to both countries. comparing this with your answer to part a, are the events independent? explain why or why not. (page 119 may ) c. using the %’s given, make a venn diagram to display this information. (don’t use your answer to part a.) d. using the conditional probability formula (page 114 in the book) and the %’s given, find the probability that a randomly-selected person has traveled to canada, if we know they have traveled to mexico.
