After giving a test to a group of students, below is the summary of grades and gender.

A	B	C	Total
Male	19	18	20	57
Female	8	16	7	31
Total	27	34	27	88

If a student was randomly chosen, find the probability that the student earned a B. Round your answer to three decimal places.

To find the probability that a randomly chosen student earned a grade of B, we need to use the formula for probability:

\[
P(\text{B}) = \frac{\text{Number of students who earned B}}{\text{Total number of students}}
\]

From the data provided, the total number of students who earned a grade of B is 34, and the total number of students in the group is 88.

Thus, the probability is:

\[
P(\text{B}) = \frac{34}{88}
\]

Now, we compute this and round it to three decimal places.

\[
P(\text{B}) \approx \frac{34}{88} \approx 0.386
\]

So, the probability that a randomly chosen student earned a B is approximately **0.386**.
