Answer: 
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%
8.6x + 3 + 8.6+3 =. 17.2x + 6
5.2+5.2= 10.4
17.2x + 6 = 10.4
