Explanation:

Step1: Identify target customer count

From the table, the number of customers who ordered regular coffee without milk is 10.

Step2: Identify total customer count

The total number of customers is 36.

Step3: Calculate probability

Probability = $\frac{\text{Target count}}{\text{Total count}} = \frac{10}{36} = \frac{5}{18}$

Answer:

B. $\frac{5}{18}$
