The probability of getting a head in all the six tosses is $\frac{1}{64}$.
We know that the probability of getting a head in a single toss of the coin is as given below: Number of favorable out comes $n\left( e \right)=1$ (head) Number of total out comes $n\left( s \right)=2$ (head and tail) $P\left( \text{head} \right)=\frac{1}{2}$ And the probability of getting a head in all the six tosses is as follows: \begin{align} & P\left( \text{six heads} \right)=\frac{1}{2}\times \frac{1}{2}\times \frac{1}{2}\times \frac{1}{2}\times \frac{1}{2}\times \frac{1}{2} \\ & =\frac{1}{64} \end{align} Hence, the probability that a head will come in all the six tosses is $\frac{1}{64}$.
