Question

over a weekend, brody counted the number of single - scoop ice creams ordered at his store. he tracked the flavors and the day on which it was ordered.

	saturday	sunday
vanilla	2	2

what is the probability that a randomly selected ice cream was ordered on a sunday and was vanilla?
simplify any fractions.

Explanation:

Step1: Calculate total ice - cream orders

We sum up the number of ice - cream orders for all categories. The total number of ice - cream orders is $(9 + 7+2 + 2)=20$.

Step2: Calculate number of Sunday and vanilla orders

The number of ice - cream orders that were on Sunday and vanilla 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 ice - cream was ordered on a Sunday and was vanilla is $\frac{2}{20}=\frac{1}{10}$.

Answer:

$\frac{1}{10}$
