How many 5-digit numbers can be formed using the digits 1, 2, 3, 4, 5, 6, 7, 8, and 9 if the first digit cannot be 8? repeated digits are allowed. How many combinations are there in a 7 digit number? How many different 4-digit codes can be made if the ...
If the sum is too large, you can repeat the process until you can tell whether it is a multiple of three. This is the basis for the solution. Since the last two digits are 23, the sum of the digits is 2+3=5 (therefore it is not divisible by three). However certain numbers can...
The total number of combinations for this case is calculated as follows:- First digit: 8 options (1-9 excluding 5)- Second digit: 8 options (remaining digits including 0)- Third digit: 7 options (remaining digits) So, the total for this case is:8×8×7=448 Step 4: Combine both case...

There are 9 letters in "telephone". We are using permutations instead of combinations because order matters ("tele" and "elet" are not the same thing). Total permutations of 4 letters from 9: 9P4 = 9!/5! = 3024 However, note that "e" appears 3 times. This will lead to...
However, there’s a shortcut to finding 5 choose 3. The combinations formula is: nCr = n! / ((n – r)! r!) n = the number of items. r = how many items are taken at a time. The ! symbol is a factorial, which is a number multiplied by all of the numbers before it...
How many sets of three numbers are there from a set of n numbers? How many elements are in the intersection of sets A' and B? What are the subsets of rational numbers? how many ternary (0, 1, 2) sequences of length 10 are there without any pair o...
Example 5 – Finding a Combination of a Given Number of Ingredients Suppose we have a dataset of 7 different ingredients for making a burger. We’ll take 4 ingredients and see how many different combinations are possible. We can take 4 ingredients from 7 in 35 different ways. We’ll store...
That's why there are letters used—specifically, the letters A, B, C, D, E, and F. Using this combination, there are 1664possible combinations (1.1579 novemvigintillion) that can be generated using a hash function that generates a 64-digit hash. One novemvigintillion is a 1 followed ...
