In this question what if we add the clause
one must choose at least 3 toppings out of 6. How can this be solved with Choice method?

And using combinations for the same problem

Is this the correct ans?

Why 6?

Oh forgot to mention
I assumed there’s 6 toppings instead of 4

Then yes it would make sense.

[taseenjubair]

But is it possible to do it using the choice method?

Not fully - it’s no longer a blanket “take or don’t take” case. You could do ALL - none - one - two though, and use the choice method for ALL.

I see.
