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 VanillaSaturday 7 2Sunday 9 2What is the probability that a randomly selected ice cream was ordered on a Sunday and was vanilla?Simplify any fractions.
Solution
To solve this problem, we first need to find the total number of ice creams ordered over the weekend.
From the table, we can see that:
- On Saturday, 7 chocolate and 2 vanilla ice creams were ordered, making a total of 7 + 2 = 9 ice creams.
- On Sunday, 9 chocolate and 2 vanilla ice creams were ordered, making a total of 9 + 2 = 11 ice creams.
So, the total number of ice creams ordered over the weekend is 9 (Saturday) + 11 (Sunday) = 20 ice creams.
Next, we need to find the number of vanilla ice creams ordered on Sunday, which from the table is 2.
The probability that a randomly selected ice cream was ordered on a Sunday and was vanilla is therefore 2 (vanilla ice creams on Sunday) / 20 (total ice creams) = 1/10.
