Question
Snow White met the old witch who became the evil queen. The old witch had 10 apples in total. Unlike in the fairy tale, this time the old witch asked Snow White to choose which apple to eat. What is the probability that Snow White will eat the poisonous apple?
Solution
The problem does not specify how many of the 10 apples are poisonous. If we assume that only one apple is poisonous (as in the original fairy tale), then the probability that Snow White will choose the poisonous apple is 1 out of 10.
The probability of an event is calculated as the number of favorable outcomes divided by the total number of outcomes. In this case, the favorable outcome is choosing the poisonous apple, and the total number of outcomes is the total number of apples.
So, the probability that Snow White will eat the poisonous apple is 1/10 = 0.1 or 10%.
