A single coin is tossed 300 times . Heads were observed 180 times . What is the long run relative frequency of tails ? In decimal form

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

Tails 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.
