Answer:
441
Step-by-step explanation:
You need to find the number of permutations of the 6 different letters, taken 3 at a time.
Therefore the sample space is 120 possible outcomes.
The way to write this expression in mathematics is A'∩B
<h3>How to solve for the expression</h3>
In order to get the right way to write this expression we have to break it down in two parts.
First we are told that some of the elements are not in A.
This is represented as A'.
Then we are told that they are in the set B. Hence we have it written as B.
Then the expression not in set A but are in set B would be written as
A'∩B.
