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 total number of tosses is 300. If heads were observed 180 times, then tails must have been observed 300 - 180 = 120 times.

The relative frequency of tails is calculated by dividing the number of tails observed by the total number of tosses:
Relative frequency of tails = 120 / 300 = 0.4

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