Final answer:
The probability that a randomly selected ice cream was ordered on a Saturday and was vanilla is 3/14.
Step-by-step explanation:
To find the probability that a randomly selected ice cream was ordered on a Saturday and was vanilla, we need to divide the number of ice creams that fit this condition by the total number of ice creams.
From the information given, we can see that there were 3 vanilla ice creams ordered on a Saturday.
The total number of single scoop ice creams ordered is 14. So the probability is 3/14, which can't be simplified further.
