Answer: It is independent.
Step-by-step explanation: The decision of Samir to buy a house in a new neighborhood and the decision of Carson to buy a different house in the same neighborhood are independent events. They are not dependent on each other and their actions do not affect the outcome of the other person's decision. The fact that they both bought houses in the same neighborhood is a coincidence and does not impact the outcome of either decision. Samir's decision to buy a house is not affected by Carson buying a house in the same neighborhood and vice versa.
