Step-by-step explanation:
If the coin is thrown three times=>
S = [ HHH, HTH, THH, TTH, HHT, HTT, THT, TTT ]
n(S) = 8
Event A: getting heads all three times
A= [ HHH ]
n(A) = 1
P(A) = n(A) / n(S) = 1/8
Hope it helps uh!!!!!

If a coin is thrown three times what is the probability of getting heads all three time?
Following are the outcomes possible when a coin is tossed three times,
S = {HHH, TTT, HTT, HHT, HTH, TTH, THT, THH}
n(s) = 8
A = getting heads all the three times
A = {HHH}
n(A) = 1
P(A) =
Therefore, the probability of getting heads all the three times is 1/8.
