Q2: Four friends each flipped a coin different numbers of times. Alice got heads 75% of the time. Mary got heads 8 out of 10 times. Sarah got heads 17 out of 20 times. Ellen got heads 35 of the time. Who had the greatest percentage of heads?
You should start by converting them all to percentages to make the question easier in the end. Alice got 75%, Mary got 8/10=80%, Sarah got 17/20=85% and Ellen got 35%. Sarah had the greatest percentage.
