In this question, we have to form 3 element subsets from {0,2,4,6,8}.

It will be same as selecting 3 elements from the given elements.

But in the question, there is additional condition mentioned that the subset should contain 6 but it should not contain 8.

Now, we need to definitely select 6 (1C1 ways) and select two elements from 0, 2, 4 (3C2 ways).

So, total number of ways will come out to be 1C1 × 3C2 = 3 ways.
