In how many ways can letters be chosen from , assuming that the order of the choices doesn't matter and that repeats are not allowed?
To find the number of ways to choose letters from a given set, assuming that the order of the choices doesn't matter and repeats are not allowed, we can use the concept of combinations.
The formula for combinations is given by:
C(n, r) = n! / (r! * (n-r)!)
Where:
C(n, r) represents the number of combinations of choosing r items from a set of n items (in this case, letters).
n! represents the factorial of n, which is the product of all positive integers up to n.
In your case, the number of letters to choose from is 'n', and you haven't mentioned the specific value of 'n'. Please provide the value of 'n' so that I can provide you with the accurate result.
