Two friends each choose a slice of pizza with one topping. The available toppings are tomatoes (T), jalapeños (J), onions (0), and eggplant (E). Use the Multiplication Counting Principle to find the total number of possible toppings combinations chosen between the two friends. Then, write an organized list using the format (Friend 1, Friend 2) to represent the sample space. Scan for Multimedia 4. Complete the table to represent the sample space of two-digit numbers using the digits 1, 4, 5, and 9. Use the row labels as the tens digits and the column labels as the ones digits to complete the table.
