How many 4 digit permutations of the 10 digits are there if no digit may be repeated?
To have no repeated digits, all four digits would have to be different, which is selecting without replacement. We could either compute 10 · 9 · 8 · 7, or notice that this is the same as the permutation 10P4 = 5040.
What is the sum of all the 4 digit numbers that can be?
Therefore, 4*3*2*1 = 24 such 4-digit numbers can be formed. In the 24 numbers formed each of the 4 digits will occur a total of 6 times in each position. Therefore, the total sum of the digits in each position is 6*(3+4+5+6) = 108. = 119988.
How many 4 digit numbers can be formed using the digits 2 3 4 and 5 with repetition?
However, 4325 is also a multiple of 625 in which the only digits used are in the set {2,3,4,5,6,7} and no digits are repeated. Therefore, there are 24−1=23 numbers that satisfy the given condition.
How many different 4 digit even numbers can be formed?
48 four digit
