A basket of fruits contains 10 bananas, 5 mangoes, and 5 apples. A fruit is selected at random. Calculate the probability of selecting an apple or a banana. Express the answer in percent form.(1 point)
There are a total of 10 + 5 + 5 = 20 fruits in the basket.
The probability of selecting an apple or a banana is (number of apples + number of bananas) / total number of fruits.
So, the probability is (10 + 5) / 20 = 15 / 20 = 0.75.
Converting to percent form, the probability is 0.75 * 100% = 75%.
Therefore, the probability of selecting an apple or a banana is 75%.
