To find the probability of picking 1 good and 1 bad apple, first calculate the total number of apples, which is 8 (5 good + 3 bad). The total ways to choose 2 apples from 8 is given by the combination formula
where
is the total number and
is how many we’re choosing. So,
.
Next, to find the number of ways to pick 1 good and 1 bad apple, calculate the combinations separately:
(for good apples) and
(for bad apples). Since we pick one good and one bad, we multiply the two values:
.
Finally, the probability of picking 1 good and 1 bad apple is the number of favorable outcomes divided by the total outcomes:
. Thus, the probability is approximately 0.536 or 53.6%.
