If a spinner has 5 possibilities, from 1 to 5, and you spin it 2 times and add the numbers, how many possibilities are there?

To answer this question, we need to consider all possible outcomes when spinning the spinner twice.

1. For the first spin, there are 5 possibilities: you can get a 1, 2, 3, 4, or 5.
2. For the second spin, there are also 5 possibilities: you can get a 1, 2, 3, 4, or 5.

Now, we need to consider all possible sums of these outcomes. The smallest sum you can get is 2 (1+1) and the largest sum is 10 (5+5).

So, the possible sums are: 2, 3, 4, 5, 6, 7, 8, 9, 10.

Therefore, there are 9 possible outcomes when you spin the spinner twice and add the numbers.
