The percentage of pizzas with both pepperoni and black olives is 33.33%
From the table :
- Total number of pizza combinations available = 12
- Number of pizzas with black olives and pepperoni = 4
Calculating the percentage:
- (Number of pizzas with black olives and pepperoni / Total number of pizza combinations available) × 100%
Now we have :
(4 /12) × 100%
= 0.333 × 100%
= 33.3%
