Answer
The probability of getting a head in all the six tosses is $\frac{1}{64}$.
Work Step by Step
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 $\frac{1}{64}$.
