To find the probability of selecting an apple or an orange from the basket, we first need to determine the total number of fruits and the number of favorable outcomes.
-
Total number of fruits:
- Apples: 20
- Watermelon slices: 4
- Oranges: 12
Total fruits = 20 + 4 + 12 = 36
-
Number of favorable outcomes (selecting an apple or an orange):
- Number of apples: 20
- Number of oranges: 12
Total favorable outcomes = 20 + 12 = 32
-
Probability formula: \[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \] \[ P(\text{apple or orange}) = \frac{32}{36} \]
-
Simplifying the fraction: \[ \frac{32}{36} = \frac{8}{9} \]
Therefore, the probability of selecting an apple or an orange is \( \frac{32}{36} \).
Among the provided options, the correct answer is:
32 over 36.
