A basket fruits contains 10 bananas, five mangoes, and five apples. A fruit was selected at random. Calculate the probably of selecting an apple or a bananas express the answer in present form.
To calculate the probability of selecting an apple or a banana, we first add the number of apples and bananas in the basket: 10 bananas + 5 apples = 15 total apples or bananas.
Then we divide the number of apples and bananas by the total number of fruits in the basket: (10 bananas + 5 apples) / (10 bananas + 5 mangoes + 5 apples) = 15 / 20 = 3/4.
Therefore, the probability of selecting an apple or a banana from the basket is 3/4 or 0.75.
