Each of three friends flips a coin 74 times. The results for each friend are shown in the tables. Find the relative frequency for the event "heads" for each friend. If the friends combine their results to get 121 heads and 101 tails, what is the relative frequency for the event "heads"? Use pencil and paper. Suppose each friend flips a coin 740 times. Is there a value you would expect the relative frequency for the event "heads" to be close to?
