2. Sophia is considering buying a dress and a necklace. The probability she will buy a red dress is 0.2, and similarly, it is 0.4 for a blue dress. There is a 10% chance she will buy a necklace. Find the probability of buying at least one of the previous items, given that she will buy at most one dress, and buying a necklace is independent of buying a dress. Assume Event A: she buys a red dress; Event B: she buys a blue dress; Event C: she buys a necklace.
