A single coin is tossed 400 times. Heads were observed 240 times. What is the long-run relative frequency of tails?

Question

A.) .30
B.) .40
C.) .60
D.) .50

Answer 1

B.) .40

Explanation:
The total number of times the coin was tossed was 400, so the total number of tails observed would be 400 - 240 = 160.
Therefore, the relative frequency of tails would be 160/400 = 0.40 or 40%.
