I'm tentatively changing my answer to say this kind of relies on practical knowledge of how stores tend to operate. If 20 coupons are given out, the store has sold all 500 shirts, arguably at a loss to the retailer. They have to have more shirts in stock to be sold at full price because, well, that's how they make money. It's more likely that such a store would carry more than just 500 shirts at the start of each day, so A is (probably) wrong.

4/1. ( not so sure tho)
Step-by-step explanation:
=[(6/6)×(6/6)] + [(5/6)×(6/6)] + [(6/6)×(5/6)]
=(36/36) + (30/36) + (30/36)
=(taking LCM) 96/36
=4/1.
hope this helps
