Question

A coin is tossed three times. what is the probability of getting two heads and one tail?

Answer 1

50% for the two heads and 25% for the one tail

Answer 2

If the order doesn't matter, then the probability is 37.5%
If it has to be head head tail, then the probability is 12.5%

If the order doesn't matter, the possible outcomes that have two heads and one tail are HHT, HTH, and THH. Since these all have a probability of 12.5% of occuring, the probability of any of them occuring is 37.5%
