A Correct answer
Explanation

Total tosses are 200 and heads appeared 120 times, so tails appeared 200 - 120 = 80 times. The probability of getting a tail is 80/200, which simplifies to 8/20 or 2/5.

AI explanation

Using the empirical probability formula, the probability of an event equals the number of times it occurs divided by the total number of trials. If heads appeared 120 times out of 200 tosses, tails appeared 80 times. The probability of getting a tail is 80/200, which simplifies to 2/5. The probability is 2/5.
