Answer:
The correct answer is
Step-by-step explanation:
A fair coin is tossed three times in a succession the sample space is shown where h represents a head and t represents a tail.
Let the experiment A denote that we get exactly one tail in three successive toss of a coin.
Sample space = { hhh, hht, hth, thh, tth, tht, htt, ttt} = 8
Favorable sample = { hht, hth, thh } = 3
Probability of the A = =
= 0.375.
Thus the probability of getting exactly one tail in three successive toss of a fair coin is given by 0.375
