To determine how many certified nurses the program should expect, we can follow these steps:
-
Calculate the number of students in the nursing program:
- \( \text{Total students} = 1800 \)
- \( \text{Students in nursing program} = \frac{2}{5} \times 1800 \)
\[ \text{Students in nursing program} = \frac{2}{5} \times 1800 = 720 \]
-
Calculate how many of those students complete the course and pass the boards:
- Only \( \frac{1}{5} \) of the nursing students complete the course.
- \( \text{Certified nurses} = \frac{1}{5} \times 720 \)
\[ \text{Certified nurses} = \frac{1}{5} \times 720 = 144 \]
Thus, the number of certified nurses the program should expect is 144.
The correct answer is B.
