MaxineTo calculate the total number of combinations of a 4-digit number using the numbers 1-9 and 0, we use the formula for permutations with repetition, which is n^r, where n is the number of options for each digit (10 in this case) and r is the number of digits (4 in this case). So, the total number of combinations is 10^4 = 10,000. Each combination will be unique, as the order of the digits matters in a 4-digit number.
Well, honey, there are 10 choices for the first digit, 9 choices for the second digit (since you can't repeat the first one), 8 choices for the third digit, and 7 choices for the fourth digit. Multiply all those together and you get 10 x 9 x 8 x 7 = 5,040 possible combinations. Hope that helps, sugar!
Oh, dude, that's a lot of combinations! So, if you're using all the numbers 0-9 to make a 4-digit number, you'd have 10 options for each digit, right? So it's like 10x10x10x10, which is 10,000 possible combinations. But like, who has time to list all that out? Just trust me, it's a bunch.

How many 3 digits combinations can be made from 1234567890?
To calculate the number of 3-digit combinations that can be made from the numbers 1-9, we can use the formula for permutations. Since repetition is allowed, we use the formula for permutations with repetition, which is n^r, where n is the total number of options (10 in this case) and r is the number of digits in each combination (3 in this case). Therefore, the total number of 3-digit combinations that can be made from the numbers 1-9 is 10^3 = 1000.
How many 3 number combinations are possible with numbers 1234?

What would the median number be of the numbers 1234567890?
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).
How many combinations are there in 4 numbers?
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.
