One of the three contestants will be randomly selected to win a prize. One of three different prizes will be randomly awarded to the contestant whose name is selected to win. What is the probability that Whitney will win Prize 2?

The table shows all the possible outcomes for flipping a coin and spinning the pointer of a spinner with four equal-sized sections labeled 1 through 4. What is the probability that the pointer will stop on 3 and the coin will land on heads? Write your answer as a percentage.

What is the probability that the pointer will stop on an odd number and the coin will land on heads? Write your answer in decimal form.

A fair coin is tossed three times in succession. The sample space is shown, where H represents a head and T represents a tail. Find the probability of getting exactly two heads.
