suppose we want to choose 6 letters without replacement from 13 distinct letters. A) how many ways can this be done if order does not matter? B) how many ways can this be done if order of choices matters

A) 1716   B) 1235520

Step-by-step explanation:

Given, Total distinct letters = 13

To choose = 6 letters

A) Number of ways to choose (if order does not matter)=

B) Number of ways to choose (if order matters)=

Hence, A) 1716   B) 1235520

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

it should be a.
