I need to calculate the possible combinations for 8 characters password. The password must contain at least one of the following: (lower case letters, upper case letters, digits, punctuations, special characters). Assume I have 95 ascii characters (lower case letters, upper case letters, digits, punctuations, special characters).

64 unique combinations (order does matter; items cannot repeat) Unique combinations (order does matter; items repeat) combinations with 1 item 4 combinations with 2 items 4^2 = 4*4 = 16 combinations with 3 items 4^3 = 4*4*4 = 64 combinations with 4 items 4^4 = 4*4*4*4 = 256 ANSWER: 340 unique combinations (order does matter; items repeat)

I want to calculate ho many combinations there are which follow this rule: let's fix A1, then cycle on all the others variables which can assume 3 values each; then let's move on to A2 and calculate again all the combinations by cycling over the 2 remaining variables (which can assume 3 values each); same thing for A3. Once I am done with A I ...

I want to find how many different combinations of the items there are. Notice: The combinations will always have 1 item from every list; The 1st item in every combination will be chosen from the 1st list, the 2nd from the 2nd etc. So, basically the first 5 combinations would be: apples - a - black - 1; apples - a - black - 2; apples - a - white - 1

$\begingroup$ So since there are 3.2333E+19 possible combinations remaining, and each of those has at least 1 digit, and the most digits it can have is 7, wouldn't the answer be 6/7's of the 3.2333E+19 = 2.77143E+19? $\endgroup$ –

Apr 19, 2017 · Hello, I have to solve a problem to calculate all the possible combinations in a dataset. I have candles and each one has 4 values: open, close, high and low. And I have a high number of candles (hundreds). I want to know all the possible scenarios that it's possible to obtain with 2 consecutive candles. For example, I have a candle:
