With identity theft on the rise, it is important that online websites, especially banking and credit card sites, require longer pin numbers. Complete each part of the assessment below.
Genuine Bank’s website requires that your pin number only be two numerical digits long. So, the first number to choose is from set A below and the second number to choose is from set B below. Find the cross product A × B to determine the number of possible combinations.
A = {0, 2, 4, 6, 8}
B = {1, 3, 5, 7, 9}
Valliant Bank’s website requires that your pin number be two digits l

Answer 1

25 number of combinations.

Answer 2

For both of them ?

Answer 3

Your second question isn't completely posted, but 25 for the first question, because there are five possible numbers from set A and five from set B - just multiply 5 x 5 to get the answer..

Answer 4

Valliant Bank’s website requires that your pin number be two digits long, the first must be a v or b and the second digit must be a number from 1 to 5. Find the cross product C × D to determine the number of combinations possible.
C = {v, b}
D = {1, 2, 3, 4, 5}
What is the difference in the number of possible pin numbers between Genuine and Valliant Banks? Which bank would you be more comfortable using if you were concerned with identity theft? Why? Explain your answers in complete sentences with proper grammar.

here is the other half and thank you (:

Answer 5

The answer is 10 for this one because for each possible first digit, there are five possible second digits. 2 x 5 = 10.

If someone is concerned with identity theft, they would be more confortable using Genuine Bank, because it would be harder to find out someone's pin number, because of the higher number of possibilities, which would decrease the persons' risk of identity theft.
