Question

A fair coin is tossed two times in succession. the set of equally likely outcomes is {hh, ht, th, tt}. find the probability of getting the same outcome on each toss.

Answer 1

The two outcomes with tail on the second toss is HT and TT, and there are two other options (HH and TH) giving you two desired outcomes out of a possible 4, which is a probability of 2/4 = 1/2 = 0.5 or 50%. 1/2 or .50% is the probability of getting the same outcome on the second toss.
