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

Answer 1

First, we calculate the total number of fruits in the basket: 10 bananas + 5 mangoes + 5 apples = 20 fruits.

The probability of selecting an apple or a banana is the sum of the probability of selecting an apple and the probability of selecting a banana.

Probability of selecting an apple = Number of apples/Total number of fruits = 5/20 = 1/4
Probability of selecting a banana = Number of bananas/Total number of fruits = 10/20 = 1/2

Probability of selecting an apple or a banana = Probability of selecting an apple + Probability of selecting a banana = 1/4 + 1/2 = 3/4

Now, we convert this probability into percentage form:
3/4 = 0.75 = 75%

Therefore, the probability of selecting an apple or a banana is 75%.
