To find the probability of selecting an apple or a banana from the basket of fruits, we first need to determine the total number of fruits and the number of favorable outcomes.
-
Total fruits in the basket:
- Bananas: 10
- Mangoes: 5
- Apples: 5
Total = 10 + 5 + 5 = 20 fruits
-
Favorable outcomes (selecting an apple or a banana):
- Apples: 5
- Bananas: 10
Total favorable outcomes = 5 (apples) + 10 (bananas) = 15
-
Probability of selecting an apple or a banana: \[ P(\text{apple or banana}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of fruits}} = \frac{15}{20} = \frac{3}{4} \]
-
Convert to percent: \[ P(\text{apple or banana}) = \frac{3}{4} \times 100 = 75% \]
So the probability of selecting an apple or a banana is 75%.
