When a customer goes to the supermarket to buy something we predict that the probability that a customer wants to buy product A is equal to 0.5 and for product B the probability is 0.6. We assume that product A and B do not influence and the motivation to buy the products is also independent from each other. What is the probability that someone simply wants to buy one product A or one product B want to buy?
The correct answer is: 0.5
