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 (apples and bananas in this case).
-
Total fruits:
- Bananas: 10
- Mangoes: 5
- Apples: 5
Total = 10 + 5 + 5 = 20 fruits
-
Favorable outcomes (apples and bananas):
- Apples: 5
- Bananas: 10
Total favorable outcomes = 5 (apples) + 10 (bananas) = 15
-
Calculating probability: \[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of fruits}} \] \[ \text{Probability} = \frac{15}{20} = 0.75 \]
-
Convert to percent: \[ 0.75 \times 100% = 75% \]
Therefore, the probability of selecting an apple or a banana is 75%.
