1. what is the probability of getting exactly one heads from three coin tosses?
is the answer 1/8?
2. what is the probability that a fair coin will land heads up three times in a row?
is the answer 3/2?

1. No. Of the eight possible outcomes, three have only one heads. So the answer is 3/8
2. No. A probability cannot exceed 1. Think again.
