OK the correct answer isIf we are given that exactly 2 heads occur, the likely outcome are, HHT,HTH,THH. From these three possible outcomes, two outcomes (HHT and THH) have 2 heads in a row.
Therefore the probability of getting 2 heads in a row is 2/3.
Therefore the probability of getting 2 heads in a row is 2/3.
