Question 1160929
Solution.
Let head be H and tail be T.
Total outcomes
HHH
HHT
HTH
HTT
TTT
TTH
THT
THH
Favorable outcomes
HHH
HHT
HTH
HTT
TTH
THT
THH
P(A) = probability of an event "A"
n(F) = number of favorable outcomes
n(T) = number of total outcomes
P(A) = n(F)/n(T)
P(A) = 7/8 = 0.875
So the answer is A.
