For a fair coin, the probability of getting tails on one flip is 0.5. Since the flips are independent, we can use the formula for expected value: E(X) = np, where n is the number of flips and p is the probability of getting tails on one flip. So, E(X) = 10(0.5) = 5. Therefore, the expected frequency of tails is 5.
