A) A single coin is tossed 300 times. Heads were observed 180 times. What is the long-run relative frequency of tails? Express the answer in decimal form. (1 point)

Answer 1

The long-run relative frequency of tails can be calculated by subtracting the relative frequency of heads from 1, since there are only two possible outcomes (heads and tails) when flipping a coin.

Relative frequency of heads = 180/300 = 0.6

Relative frequency of tails = 1 - 0.6 = 0.4

Therefore, the long-run relative frequency of tails is 0.4.
