The local high school is hosting an ice cream social for new students. They record the ice cream choices of the students throughout the event.

What is the probability that a person who chose vanilla ice cream is male?

\begin{tabular}{|c|c|c|c|c|}
\hline & Vanilla & Strawberry & Chocolate & Total \\
\hline Male & 6 & 4 & 13 & 23 \\
\hline Female & 8 & 9 & 4 & 21 \\
\hline Total & 14 & 13 & 17 & 44 \\
\hline
\end{tabular}

A. [tex]$\frac{6}{23}$[/tex]
B. [tex]$\frac{4}{7}$[/tex]
C. [tex]$\frac{3}{7}$[/tex]
D. [tex]$\frac{3}{22}$[/tex]



Answer :

To determine the probability that a person who chose vanilla ice cream is male, follow these steps:

1. Identify the relevant data from the table:
- The number of males who chose vanilla ice cream: 6
- The total number of people who chose vanilla ice cream: 14

2. Understand what we need to find:
- We want the probability that a person who chose vanilla ice cream is male, which can be found using the formula of conditional probability:
[tex]\[ P(\text{Male | Vanilla}) = \frac{\text{Number of males who chose vanilla}}{\text{Total number of people who chose vanilla}} \][/tex]

3. Plug in the numbers from the table into the formula:
[tex]\[ P(\text{Male | Vanilla}) = \frac{6}{14} \][/tex]

4. Simplify the fraction if possible:
[tex]\[ \frac{6}{14} = \frac{3}{7} \][/tex]

Thus, the probability that a person who chose vanilla ice cream is male is [tex]\(\frac{3}{7}\)[/tex]. Converted to a decimal, this is approximately:
[tex]\[ 0.42857142857142855 \][/tex]

Given this calculation, the correct option among the provided choices is:
C. [tex]\(\frac{3}{7}\)[/tex]
