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=(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=(1)/(2)*(1)/(2)=(1)/(4)`

In percentage form, the probability is given to be:

`\begin{gathered} P=100*(1)/(4) \\ P=25\% \end{gathered}`

The probability is 25%.
