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.

	chocolate	vanilla
sunday	9	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 number of ice - creams

Add up all the values in the table. \(7 + 2+9 + 2=\) \(20\)

Step2: Find the number of Sunday - vanilla ice - creams

From the table, the number of Sunday - vanilla ice - creams is \(2\)

Step3: Calculate the probability

Probability \(P=\frac{\text{Number of Sunday - vanilla ice - creams}}{\text{Total number of ice - creams}}\)
\(P = \frac{2}{20}=\frac{1}{10}\)

Answer:

\(\frac{1}{10}\)
