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)

1 answer

The long-run relative frequency of tails can be calculated by subtracting the number of times heads were observed from the total number of tosses, and then dividing by the total number of tosses.

Total number of tosses = 300
Number of times heads were observed = 180

Number of times tails were observed = 300 - 180 = 120

Long-run relative frequency of tails = 120 / 300 = 0.4

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