A box of chocolates contains 20 identically shaped chocolates. Five of them are filled with jelly, three are filled with caramel, and twelve are filled with nuts. What is the probability that one chocolate chosen at random is filled with jelly, caramel, or nuts?

The probability is exactly one. All the chocolates are filled with either jelly, caramel, or a nut.

Thanks bobpursley, I appreciate your help.

To find the probability of choosing a chocolate filled with jelly, caramel, or nuts, we need to calculate the ratio of the total number of chocolates filled with jelly, caramel, or nuts to the total number of chocolates in the box.

1. Start by adding the number of chocolates filled with jelly (5), caramel (3), and nuts (12) together: 5 + 3 + 12 = 20.
2. This gives us the total number of chocolates filled with jelly, caramel, or nuts.
3. Now, determine the total number of chocolates in the box, which is given as 20.
4. The probability of selecting a chocolate filled with jelly, caramel, or nuts is the ratio of the total number of chocolates filled with jelly, caramel, or nuts to the total number of chocolates in the box.
5. So, the probability is 20/20, which equals 1.

Therefore, the probability that a randomly chosen chocolate from the box is filled with jelly, caramel, or nuts is 1 or 100%.
