we got 10 digits to choose from for the first digit, 9 for the second and so on

scenarios that got no repeated digits.

the total number of possible PINs with 6 digits is

or just 10⁶

so the fraction we are looking for is the number of valid states decided by all possible states.

=0.1512

rounded to the nearest thousandth it's

0.151

(actually, I didn't expect the probability to be around 15 percent)

hope it helps. asked question whenever you like

kind regards

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;
