Answer:

0.015

Step-by-step explanation:

We know that 30% of the customers are students, and 5% of these students order decaf coffee, so we can say that 5% of that 30% (=1.5%) is the percentage of customers that are students and order decaf coffee.

So, the probability of randomly selecting a customer that is a student and orders decaf coffee is 1.5% = 0.015

The percentage of customers that order decaf coffee (10%) is not applied in this solution, as we can have the percentage of students that order decaf coffee just using the percentage of customers that are students, and the percentage of students that order decaf coffee.
