The table below shows data about student involvement in extracurricular activities at a local high school. What is the probability that a randomly chosen student is male and involved in extracurricular activities?

\begin{tabular}{|c|c|c|c|}
\hline & Involved in Activities & Not Involved in Activities & Totals \\
\hline Male & 112 & 145 & 257 \\
\hline Female & 139 & 120 & 259 \\
\hline Totals & 251 & 265 & 516 \\
\hline
\end{tabular}


Sagot :

To determine the probability that a randomly chosen student is a male who is involved in extra-curricular activities, we need to follow these steps:

1. Identify the number of male students involved in extra-curricular activities: According to the table, this number is [tex]\(112\)[/tex].

2. Identify the total number of students: The table shows that there are [tex]\(516\)[/tex] students in total (sum of all students in the table).

3. Calculate the probability: Probability is found by dividing the number of favorable outcomes (male students involved in activities) by the total number of possible outcomes (total students).

[tex]\[ \text{Probability} = \frac{\text{Number of male students involved in activities}}{\text{Total number of students}} = \frac{112}{516} \][/tex]

4. Express the probability as a decimal: Dividing 112 by 516 gives approximately [tex]\(0.217\)[/tex].

Therefore, the probability that a randomly chosen student is a male who is involved in extra-curricular activities is approximately [tex]\(0.217\)[/tex].
