If a fair coin is tossed three times, find the probability of getting heads on the first toss and tails on the second and third tosses.

The answer is:

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:

Note probability =

homozygous. one is homozygous, while two is heterozygous.
