Question

When flipping a standard coin 2 times, what is the probability of flipping heads 2 times in a row (I need the percentage and round to the nearest whole number if necessary)

Answer 1

The probability of an event is calculated using the probability formula:

$P=\frac{\text{ number of required events}}{\text{ number of possible events}}$

Therefore, the probability of getting a head is calculated to be:

$P=\frac{1}{2}$

The probability of getting two heads will be the product of the probabilities of getting a head twice. Therefore, this will be:

$P=\frac{1}{2}\times\frac{1}{2}=\frac{1}{4}$

In percentage form, the probability is given to be:

$\begin{gathered} P=100\times\frac{1}{4} \\ P=25\% \end{gathered}$

The probability is 25%.
