Answer

Explanation:

Step1: Calculate total large orders

Add up large - sized orders of each food item. $3 + 18+6=27$

Step2: Identify total orders

The total number of orders is given as 100.

Step3: Calculate probability

Use the probability formula $P(\text{Large})=\frac{\text{Total Large orders}}{\text{Total orders}}=\frac{27}{100}$

Answer:

$\frac{27}{100}$
