Answer:
B 1/5 1/4 1/3
Step-by-step explanation:
The first digit Maggie's bank picked from the 5 digit available, so 1/5.
The second digit will be picked from the 4 remaining digits available, so 1/4.
For the final digit, the bank will have only 3 options to choose from, so 1/3.
So the possibility for the 3-digit assigned PIN to be 123 is
[tex]\frac{1}{5} * \frac{1}{4} *\frac{1}{3} =\frac{1}{60}[/tex]
1/60, so the formula is the one presented in the B option: 1/5 1/4 1/3
