The probability the coin lands tails up exactly two times is 3/8
How to determine the probability?
When a coin is flipped three times, the sample space is;
S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}
In the above sample space, there are 3 occurrences where the coin lands tail up, out of the 8 occurrences.
So, the probability is:
P = 3/8
Hence, the probability the coin lands tails up exactly two times is 3/8
