The correct answer is B. 2/5

Step-by-step explanation:

This is the information given to us:

A. Shopping preferences for the survey:

1. Mall

2. Stand-alone store

3. Online

B. Paying preferences:

1. Store card

2. Credit card

3. Cash

4. Gift card

5. Check

Assume equal probabilities within categories.

It means that each of the paying preferences has the same probability of being selected, if there are five, it means each paying preference has 1/5 of probability and if we're choosing two of them: gift card or check, we have

1/5 + 1/5 of probability = 2/5

The probability of paying by gift card or check is 2/5
