A single coin is toss 300 times heads were observed 180 times what is long run relative frequency of tales express the answer in decimal form
The long run relative frequency of tails can be calculated by dividing the number of times tails was observed by the total number of tosses.
Total number of tosses = 300
Number of times tails was observed = 300 - 180 = 120
Long run relative frequency of tails = Number 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.
