Give the step-by-step reasoning process and then the final answer. If a solver flips a coin 211 times and gets a head on 65 of the flips, how many more tails than heads did he get?
If the solver got a head in 65 of the 211 flips, he got 211 - 65 = 146 tails. The number of tails than he got more than head is 146 - 65 = 81.
The final answer: 81.
