Math Problem Statement

Find the probability that the student was male given they got a C, based on the summarized data table of grades and gender.

Solution

The question asks to calculate the probability that a student is male given that they received a grade of C. This involves conditional probability.

From the table provided:

  • Total number of students who received a grade of C: 22
  • Number of males who received a grade of C: 16
  • Conditional probability formula:
    P(Male | Grade C)=Number of males with grade CTotal number of students with grade CP(\text{Male | Grade C}) = \frac{\text{Number of males with grade C}}{\text{Total number of students with grade C}}

Substitute the values:
P(Male | Grade C)=1622=811P(\text{Male | Grade C}) = \frac{16}{22} = \frac{8}{11}

Final Answer:

The probability that the student is male, given they got a C, is:
811\boxed{\frac{8}{11}}
