Let A denote the event of placing a $ 1 straight bet on a certain lottery and winning. Suppose that, for this particular lottery, there are 3, 360

different ways that you can select the four digits (with repetition allowed) in this lottery, and only one of those four-digit numbers will be the

winner. What is the value of P(Ā)? (Round to five decimal places as needed.)
