I’m pretty confident it’s 210 because I remember the formula involves factorials, but I should double-check my notes.

I feel like I might have confused the combinations with permutations in my studies. Is it really just 7 choose 4?

I think we need to use the combination formula for this, but I'm not entirely sure how to set it up.

I remember practicing similar questions, and I think the answer is 35, but I can't recall the exact calculation.

Hmm, I'm not totally sure about this one. I know continuous reinforcement is good for quickly establishing a behavior, but I think intermittent might be better for maintaining it over time. Let me think this through a bit more.

Lists and Data Extensions seems like the safest bet to me. That way I can cover both options and not risk missing something important.
