How do you calculate combinations?
Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter. To calculate combinations, we will use the formula nCr = n! / r! * (n – r)!, where n represents the total number of items, and r represents the number of items being chosen at a time.

Can John the Ripper crack any password?
The hashing algorithm converts the raw password into a series of characters (hash) that would take a lot of time and resources to decode. This is where John the Ripper comes in. John the Ripper is a free, open-source password cracking and recovery security auditing tool available for most operating systems.
Is 11 character password strong?
When a password is properly generated, 11–15 characters will provide more than enough protection for the everyday user. However, we know that most people feel more comfortable and secure with a longer version.
How do you calculate all possible outcomes?
The fundamental counting principle is the primary rule for calculating the number of possible outcomes. If there are p possibilities for one event and q possibilities for a second event, then the number of possibilities for both events is p x q.
How do you generate all possible combinations of one list?
Add a Custom Column to and name it List1. Enter the formula =List1. Expand out the new List1 column and then Close & Load the query to a table. The table will have all the combinations of items from both lists and we saved on making a custom column in List1 and avoided using a merge query altogether!

Can a 20 character password be hacked?
The 20-bit password is half as hard to crack as a password with 21 bits. A password with 20 bits of entropy is drawn uniformly and randomly from 2²⁰ possible distinct passwords. That's just over 1 million, and approximately the strength you would get from a 4-character generated password.
How do you calculate the number of possible combinations?
To calculate combinations, we will use the formula nCr = n! / r! * (n – r)!, where n represents the total number of items, and r represents the number of items being chosen at a time. To calculate a combination, you will need to calculate a factorial.

How do you figure out combinations of a set of characters?
The formula for combinations is generally n! / (r! (n — r)!), where n is the total number of possibilities to start and r is the number of selections made. In our example, we have 52 cards; therefore, n = 52.
