1. The problem asks for the number of pizzas that have chillies on them based on the Venn diagram. 2. According to the Venn diagram, the pizzas that have chillies are the ones inside the "Has chillies" circle. 3. Inside the "Has chillies" circle only, we have: - Mexican - Pepperoni 4. In the intersection of the "Has chillies" and "Has ham" circles, we have: - Sizzler 5. These three pizzas (Mexican, Pepperoni, and Sizzler) all have chillies. 6. The right circle "Has ham" contains pizzas without chillies except the intersection which we already counted. 7. Therefore, the total number of pizzas with chillies = 2 (only chillies) + 1 (both chillies and ham) = 3.
