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.
The long-run relative frequency of tails can be calculated by subtracting the relative frequency of heads (180/300 = 0.6) from 1.
Relative frequency of tails = 1 - 0.6 = 0.4
Therefore, the long-run relative frequency of tails is 0.4.
