tossing three coins 1000 times. How many times do the three coins produce exactly two tails?

Question

Now, look at the simulation of tossing three coins 1000 times. How many times do the three coins produce exactly two tails? Divide that count by 1000 to estimate the long-term relative frequency of getting two tails and one head on any combination of the three coins.

Answer 1

EXPECTED 500 times which is 1/2 = 0.5
