Suppose a three-digit Personal Identification Number (PIN) is generated at random, with all such PINs being equally likely to be selected. Assume the digits 0--9 are available for each of the three positions, and it's okay if a digit is repeated in the PIN.What is the probability that the PIN both starts with a 4 and ends with an odd digit? Enter your response in the textbox below, and show work that illustrates your reasoning.
