Answer

Explanation:

Step1: Determine total and favorable outcomes

Total number of students is 5, and number of spots is 4.

Step2: Calculate the probability

The probability formula is $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. The number of favorable outcomes (Chandra being chosen) is 4 (since there are 4 spots), and the total number of outcomes is 5. So $P = \frac{4}{5}=0.8$.

Answer:

80%
