a store recently released a new line of alarm clocks that emit a smell to wake you up in the morning. the head of sales tracked users ages and which smells they preferred. what is the probability that a randomly selected user chose a clock scented like cinnamon and is under 13 years old? simplify any fractions.

Answer

Explanation:

Step1: Find total number of users

Add all the values in the table: $2 + 8+7 + 3=20$.

Step2: Find number of users under 13 who chose cinnamon

The number of users under 13 who chose cinnamon is 2.

Step3: Calculate probability

The probability $P$ of an event is given by the formula $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So the probability that a randomly - selected user who chose cinnamon is under 13 years old is $P = \frac{2}{20}=\frac{1}{10}$.

Answer:

$\frac{1}{10}$
