Final answer:
To find the number of customers who ordered their pizza with pepperoni or sausage (or both), we need to add the number of customers who ordered their pizza with only pepperoni, only sausage, and both pepperoni and sausage.
Step-by-step explanation:
To find the number of customers who ordered their pizza with pepperoni or sausage (or both), we need to add the number of customers who ordered their pizza with only pepperoni, only sausage, and both pepperoni and sausage.
According to the given information:
- Number of customers who ordered with only pepperoni = 19
- Number of customers who ordered with only sausage = 16
- Number of customers who ordered with both pepperoni and sausage = 15
To find out the number of customers who ordered their pizza with pepperoni or sausage (or both), we can add these three numbers:
19 + 16 + 15 = 50
Therefore, 50 customers ordered their pizza with pepperoni or sausage (or both).
