Given:

The table representing favorite ice cream of juniors and seniors.

Required:

What is the approximate probability that a student is a junior given their favorite ice cream is chocolate?

Step-by-step explanation:

The probability formula

`Probability(P)=\frac{\text{ Number of favorable cases }}{\text{ Total number of cases}}`

Total counts of favorite chocolate of juniors = 191

Number of students like chocolate ice cream = 51

So, probability

`\begin{gathered} P=(51)/(191) \\ P=26\% \end{gathered}`
