Question

CODES Use the following information to solve. A bank gives each new customer a 4-digit code number which

allows the new customer to create their own password. The code number is assigned randomly from the digits 1, 3,
5, and 7, and no digit is repeated.
8. What is the probability that the code number for a new customer will begin with a 7?

Answer 1

Step-by-step explanation: There are four possible digits that the code number can begin with: 1, 3, 5, or 7. Since each of these digits is equally likely to be selected, the probability of the code number beginning with a 7 is 1/4 or 0.25. Therefore, the probability that the code number for a new customer will begin with a 7 is 0.25 or 25%.
