Question

Three coins will be tossed in the air at the same time, what is the probability that all 3 will land on heads? Give your answer as a percent to the nearest one decimal place

Answer 1

Number of coins are 3.

The sample space will be,

`S=\lbrace HHH,HHT,HTH,HTT,THH,THT,TTH,\text{TTT}\rbrace`

The probablity of getting all three heads is,

`\begin{gathered} P=(1)/(8)*100 \\ =12.5 \end{gathered}`

Thus, the requried probablity is 12.5%.
