210.
It can be calculated as factorial 44! = 4x3x2x1= 60
1 is one.
1680 any 4 from 8 is factorial 8 divided by factorial 4 8*7*6*5*4*3*2*1/4*3*2*1 = 8*7*6*5 = 1680
1215 - 789 = 426
This is a question of permutations; the answer is equal to the factorial of 5 (number of digits) divided by the factorial of 3 (number used in each selection), written 5! / 3!. This equals 120 / 6, or 20 ways.
This question can be answered regardless of what digits are used. If there are four options for the first digit, then there are only 3 options for the second digit, and 2 options for the third. There are no options left for the fourth and final digit. So, the answer is 4! (or four factorial).
1215 miles = 76,982,400 inches.
The number of different ways to arrange the digits 0, 1, 2, 3, and 4 is calculated by finding the factorial of the number of digits. Since there are 5 digits, the total arrangements are 5! (5 factorial), which equals 120. However, if leading zeros are not allowed, we must subtract arrangements that begin with 0. There are 4! arrangements for the remaining digits (1, 2, 3, 4), which equals 24. Thus, the valid arrangements without leading zeros total 120 - 24 = 96.
