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?
