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...

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...

(12 points) A software function generates a random number N digits long. Each digit is determined by randomly selecting a value from 0 through 9. All ten values are equally likely, and different digits may have the same value. Determine the minimum length N such that there is at least a 50% probability that at least one digit will have the value 0.

In a three-digit lottery, each of the three digits is supposed to have the same probability of occurrence (counting initial blanks as zeros, e.g., 32 is treated as 032). The table shows the frequency of occurrence of each digit for 90 consecutive daily three-digit drawings. Digit 0 1 2 3 4 5 6 7 8 9 Frequency 34 32 30 25 27 29 24 18 25 26 270 Total picture Click here for the Excel Data File (a) Calculate the...

A large collection of one-digit random numbers should have about 50% odd and 50% even digits because five of the ten digits are odd (1, 3, 5, 7, and 9) and five are even (0, 2, 4, 6, and 8) a. Find the proportion of odd-numbered digits in the following lines from a random number table. Count carefully. 9 0 49 0 5 0 7 8 1 7 8 3 4 5 0 7 1 5 7 5 1 2...

Write a C program which calculates how many digits a number has and prints each digit in reserve order with space in between(no space after the last digit). The number > 0 and has no more than 5 digits. (optional] It is better to write two functions. One is designed for printing number in reverse order and the other is for counting the number of digits. Given that the value of number (which is an int variable) is 12345, the...

A phone number is an ordered string of ten digits. Each digit is one of 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9. (a) How many phone numbers are there that do not contain any zeros? (b) How many phone numbers are there that start with 216 or 440? (c) How many phone numbers are there that start or end with 3? (d) What is the smallest number of phone numbers that guarantee at least nine of...
