A single coin is tossed 300 times heads were observed 180 what is the long run relative frequency of tails express the answer in decimal form

To find the long run relative frequency of tails, we need to first find the number of times tails were observed in the 300 tosses.

Number of tails observed = 300 - 180 = 120

Now, the relative frequency of tails is computed 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.
