Question

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.

Answer 1

The answer is:
`(1)/(8)`

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:
`(1)/(8)`

Note probability =
`(number of possible occurrence)/(number of total occurrence)`
