To solve the problem of finding the probability distribution of the number of successes in two tosses of a die, where a success is defined as "getting a number greater than 4", we will follow these steps: ### Step 1: Define the Sample Space When tossing a die, the possible outcomes are {1, 2, 3, 4, 5, 6}. In two tosses, the total number of outcomes is \(6 \times 6 = 36\). ### Step 2: Define Success A success is defined as getting a number greater than 4. The numbers greater than 4 on a die are 5 and 6. Thus, the probability of success (getting a number greater than 4) is: - Success outcomes: {5, 6} → 2 outcomes ...
