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)

To find the long-run relative frequency of tails, we need to subtract the frequency of heads from the total number of tosses and then divide by the total number of tosses.

Total number of tosses = 300
Frequency of heads = 180

Frequency of tails = 300 - 180 = 120

Long-run relative frequency of tails = Frequency of tails / Total number of tosses
Long-run relative frequency of tails = 120 / 300
Long-run relative frequency of tails = 0.4

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