A computer system uses 5 digits numerical (from 0 to 9) passwords to provide access for resources, however, only one thousand passwords are valid. If all the valid passwords begin with a number zero and the hacker knows that, what is the probability that a randomly entered password will be valid? [The answer should be a number rounded to five decimal places, don't use symbols such as %]

Suppose the probability of winning a particular lottery is 1 in 14C5•9 or 118,018. If Juanita and Michelle each play the lottery on one particular evening, what is the probability that both will select the winning numbers if they make their selections independently of each other? The probability that both will select the winning numbers is approximately nothing. (Use scientific notation. Use the multiplication symbol in the math palette as needed. Round to the nearest hundredth as needed.)
