A single coin is tossed 100 times. Heads were observed 40 times. What is the long-run relative frequency of tails? * 1 point 0.40 0.60

To find the long-run relative frequency of tails, we need to calculate the number of times tails appeared in the 100 tosses.

Since we know that heads appeared 40 times in these 100 tosses, we can deduce that tails appeared 100 - 40 = 60 times.

So, the relative frequency of tails in the long run would be 60/100 = 0.60.

Therefore, the correct answer is 0.60.
