Question

on a sample basis tray 2 out of 10 cake samples are strawberry. What is the probability that a randomly selected piece of cake will be strawberry?Write your answer as a fraction or whole number p(strawberry)=

Answer 1

Remember that the probability of an event is the number of times the event can happen divided by the number of possible event:

`P(A)=\frac{\#\text{ of times that A happens}}{\#\text{ of all outcomes}}`

In this case, we have that the tray has 10 cakes, and 2 are strawberry. Then, the probability to randomly select a strawberry cake is:

`\begin{gathered} A\colon\text{strawberry cake} \\ \Rightarrow P(A)=(2)/(10)=(1)/(5) \\ P(A)=(1)/(5)_{} \end{gathered}`
