grades and gender
\begin{tabular}{|c|c|c|c|c|}
hline
& a & b & c & total \\
hline
male & 6 & 7 & 18 & 31 \\
hline
female & 8 & 9 & 15 & 32 \\
hline
total & 14 & 16 & 33 & 63 \\
hline
end{tabular}
if one student is chosen at random, find the probability that the student was male and got a \c\. round your answer to 4 decimal places.

Explanation:

Step1: Identify favorable cases

Number of male students with "C" is 18.

Step2: Total possible cases

Total students = 63.

Step3: Calculate probability

Probability = $\frac{18}{63} \approx 0.2857$.

Answer:

0.2857
