He only multiplied 6 by 5, and forgot the r to get 30+r=96. The correct solution is 30 + 6r = 96, or 6r=66. Divide both sides by 6 to get r = 11.
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
