clearly, two of the three possible discounts will give enough discount so that the final price with tax will be less than $25.
So, probability is 2/3
Gerald found a $24.99 backpack that he’d like to purchase from the sporting goods store. The current promotion involves scratching a card to reveal a discount that can be 5% off, 15% off or 25% off. Each of the three discount options is equally likely. After the discount is taken, a 6.5% tax is added. What is the probability that Gerald will pay less than $25 to purchase this backpack? Express your answer as a common fraction.
