Hi! Please solve. Thank you!

**Problem 2.6**

Students from a particular college were asked which subject is their favorite. Find the probability of selecting a student who favored math given they were male.

The table below presents the number of male and female students who favored each subject:

| Subject  | Male | Female |
|----------|------|--------|
| Math     |  12  |   9    |
| English  |  15  |  25    |
| History  |  14  |  13    |
| Science  |   7  |   5    |

To determine the probability of selecting a male student who favored math, given that the student is male, follow these steps:

1. **Identify the total number of male students**: This is the sum of all males favoring each subject.
   \[
   \text{Total Male Students} = 12 + 15 + 14 + 7 = 48
   \]

2. **Identify the number of males who favored math**: This is provided as 12.

3. **Calculate the conditional probability**: The probability of a randomly selected male student favoring math is given by the ratio of the number of males who favor math to the total number of males.
   \[
   P(\text{Math | Male}) = \frac{\text{Number of Males Favoring Math}}{\text{Total Number of Males}} = \frac{12}{48} = 0.25
   \]

**Answer Choices:**
- .12
- about .57
- .48
- .25
- about .5

Therefore, the correct answer is **.25**.
