Question 5# (Combinations, including stars and bars') Problem: How many PINs have digit suam 20? (A PIN is string abcd of 4 decimal digits eg 6806) As a first attempt at answering this: (a) How many different solutions in non-negative integers has the equation a+b+c+d-20? Hint: 20 stars and 3 bars. The count in (a) is much too big for our problem because it includes many solutions that contain non-decimal digits; ie. values of a, b, c or d that...
Discrete Mathematics. Thank You!! 3. Using the digits 1, 2, 3 and 5, how many 4 digit numbers can be formed if a) The first digit must be 1 and repetition of the digits is allowed? (5 points) b) The first digit must be 1 and repetition of the digits is not allowed? (5 points)
PLEASE HELP WITH 2 AND 3!! THANK YOU:) 2. How many 4-digit numbers can be formed from the digits 2,3,4,5,6,7,8 if: i) Each digit may be used only once in each number? ii) Each digit may be used repeatedly in each number? 3. A bag contains five red balls numbered 1,2,3,4,5 and nine green balls numbered 6,7,8,9,10,11,12,13,14. If a ball is drawn at random what is the probability that: i) The ball is red and odd-numbered. ii) The ball is...
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...
