Answer:

The answer is: [tex]\frac{1}{8}[/tex]

Step-by-step explanation:

The sample space when tossing a coin three times is [HHH, HHT, HTH, HTT, THH, THT, TTH, TTT]  and the total number of occurrence is 8.

Getting Head on first toss, tail on second and third is: HTT and it occurs just once in our sample space.

Therefore, the probability of getting Head on first toss, tails on second and third tosses is: [tex]\frac{1}{8}[/tex]

Note probability = [tex]\frac{number of possible occurrence}{number of total occurrence}[/tex]
