There are 100 people at lunch. The fruits available for lunch are blueberries, raspberries, or blackberries.
59 people have blueberries, 37 have raspberries, and 54 have blackberries.
25 people have both blueberries and raspberries; 12 people have raspberries and blackberries; 28 people have blackberries and blueberries.
10 people have all three fruits.
How many people have no fruit at all?
To find the total amount of people, we use an algorithm.
59 + 37 + 54 - 25 - 12 - 28 + 10 = 95.
There are 95 people who have any type of fruit at all.
This means that we can find the amount of people without any fruit.
100 - 95 = 5
There are 5 people with no fruit.
I hope this helped,
