Question

What is the probability that you will flip a heads all 3 times?

Answer 1

We have:

outcomes of a coin: 2

The probability of flip head one time is:

$P(H)=\frac{1}{2}$

Therefore the probability of flip a head all 3 times is given by:

$P(HHH)=\frac{1}{2}\cdot\frac{1}{2}\cdot\frac{1}{2}=\frac{1}{8}$

Answer:

$\begin{equation*} \frac{1}{2}\cdot\frac{1}{2}\cdot\frac{1}{2}=\frac{1}{8} \end{equation*}$
