Answer

Explanation:

Step1: Identify favorable and total outcomes

Favorable outcomes are 4 (students chosen), total outcomes are 20 (total students).

Step2: Calculate probability

Probability formula is $P=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}$, so $P = \frac{4}{20}=\frac{1}{5}$.

Answer:

$\frac{1}{5}$
