To find the probability of selecting an apple or an orange, you need to calculate the ratio of the number of favorable outcomes (i.e., the number of apples and oranges) to the total number of possible outcomes (i.e., the total number of fruits in the basket).
Let's break down the process step by step:
Step 1: Find the total number of fruits in the basket.
We add up the number of apples, watermelon slices, and oranges: 20 apples + 4 watermelon slices + 12 oranges = 36 fruits in total
Step 2: Identify the number of favorable outcomes (apples or oranges).
In this case, the number of favorable outcomes refers to the number of apples and oranges in the basket: 20 apples + 12 oranges = 32 favorable outcomes.
Step 3: Determine the probability.
Probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
So, in this case, the probability of selecting an apple or an orange is: 32/36.
Simplifying the fraction by dividing both the numerator and denominator by the greatest common divisor (GCD), which is 4, we get:
Probability = (32 รท 4) / (36 รท 4) = 8/9.
Therefore, the probability of selecting an apple or an orange from the basket is 8/9, or approximately 0.89 (rounded to two decimal places).
