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 in the basket.
The basket contains:
- 10 bananas
- 5 mangoes
- 5 apples
Total number of fruits = 10 (bananas) + 5 (mangoes) + 5 (apples) = 20 fruits
Next, we need to find the number of favorable outcomes for selecting an apple or a banana:
- Number of apples = 5
- Number of bananas = 10
Number of favorable outcomes (apples + bananas) = 5 + 10 = 15
Now, we can calculate the probability of selecting an apple or a banana: \[ P(\text{apple or banana}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of fruits}} = \frac{15}{20} \]
To convert this to a percentage, we multiply by 100: \[ P(\text{apple or banana}) = \frac{15}{20} \times 100 = 75% \]
Thus, the probability of selecting an apple or a banana is 75%.
The correct answer is: 75%
