Note the probabilty of getting a tail when a coins is flipped 1 time is 1/2
Now for the probability when flipping a coin 3 times, the probability if the a single flipped is multiplied by itself 3 times..
Therefore, the probability of getting a tail for 3 times is :
[tex]\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}=\frac{1}{8}[/tex]The answer is 1/8
Another solution is to list down the possible outcomes :
HHH
THH
HTH
HHT
TTH
THT
HTT
TTT
There are a total of 8 outcomes.
and getting the probability of TTT over 8 outcomes is 1/8
