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

Answer 1

The long-run relative frequency of tails can be calculated by subtracting the relative frequency of heads from 1.

Relative frequency of heads = 240/400 = 0.6

Long-run relative frequency of tails = 1 - 0.6 = 0.4

Therefore, the long-run relative frequency of tails is 0.4 or 40%.
