what are the every 4-digit numbers that can be formed using 1234567890
6574
4 of them. In a combination the order of the numbers does not matter.
7
Ans. 4.5 Explanation: The median for an even set of numbers is (Xn+Xn+1)/2 where n = number of values in dataset divided by 2 and Xn is the nth ranked value when sorted from lowest to highest. Your ordered set is S=(0,1, 2, 3, ,...9) at least I think it is, with 10 values , X1 = 0, X2 =1, ..., so median = (4+5)/2 = 4.5. There are five numbers lower than 4.5 (0,1,2,3,4) and five numbers higher (5,6,7,8,9).
10 * * * * * That is just plain wrong! It depends on how many numbers in each combination but there are 1 combination of 4 numbers out of 4, 4 combinations of 3 numbers out of 4, 6 combinations of 2 numbers out of 4, 4 combinations of 1 number out of 4. A grand total of 15 (= 24-1) combinations.
Assuming that "number" means digits and that it is permutations (rather than combinations) that are required, the answer is 816 which is 281.475 trillion (approx).
