Introduction: Ten digit ISBN numbers are created so that the first nine digits are information digits and the last digit is a check digit. T his last number helps people notice and correct mistakes that might be made in recording the information digits. The same is true for thirteen digit ISBN numbers. Here is a ten digit ISBN number: 0-13-149498-8. The digit 0 indicates the book is written for English-speaking people. The number 13 and the number 149498 identify the...

Last two numbers digit: 11
1) (35 pts) In this problem the last two digits of your student number will be important. Let n, be a number equal to the last digit of your student number, na be a number equal to the last two digits of your student number. That is, if the last two digits of your student number is 83 then, n = 3, n2 = 83. Consider the predator-prey equations: dx =ax - bxy...

3 digits are drawn independently and at random to obtain a 3-digit number. Each of the 3 digits can take integer values 1 through 9, with each integer being equally likely to be chosen. In other words, the 3-digit number can be from 111 through 999, but any 3-digit number that contains 0 is impossible. A. What is the chance that the 3-digit number is even? B. What is the chance that the 3-digit number has at least one digit...
