Chips labeled 1 to 4 are placed in a hat. Becky randomly selects two chips from the hat without replacing the first chip before the second chip is selected. She creates a twodigit number with the first number representing the tens digit and the second number representing the ones digit. For example, if she selects a one and two, she would create the number twelve. Determine the sample space for this experiment.
