What is the probability that two six-sided dice will roll the same number?

What is the probability of rolling a seven on two six-sided dice?

For an airline, many times small cities have limited flights that go into their airports. To get a flight to Columbia, SC you must go through one of three cities: Raleigh, NC, Atlanta, GA, or Charlotte, NC. Two customers from Orlando, FL are trying to get to Columbia, SC with only one stop (one of the three above mentioned cities). Assume that they are equally likely to go through any of the above cities. What is the probability one of the customers fly through Charlotte, NC, while the other does not fly through Charlotte, NC?

If I tossed a fair coin 3 times, what is the probability of it landing on tails only once?
