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?
Question
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?
Solution
To answer this question, we need to consider all possible outcomes when spinning the spinner twice.
- For the first spin, there are 5 possibilities: you can get a 1, 2, 3, 4, or 5.
- 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.
