To determine probability, you have to divide the desired outcome by all possible outcomes. This means you have to add up the total number of notebooks sold by the store and then divide the amount of purple notebooks by that number.
Step by step:
1. Add up the total number of notebooks:
6 + 11 + 7 + 5 +3 = 32
2. Divide the number of purple notebooks by the total number of notebooks:
7/32
3. Convert 7/32 to a decimal (using a calculator):
0.21875
4. Multiply the value by 100 to get the percentage:
