Respuesta :

It is a total of 3 options choosing only two in a combination for you would use the combination "equation" :[tex] \frac{n!}{(n-r)!r!} [/tex]

There are six (6) different sandwiches available.
They are:

-- egg salad on pita
-- egg salad on baguette
-- chicken salad on pita
-- chicken salad on baguette
-- falafel on pita
-- falafel on baguette .

Some sound more appetizing than others,
but the math is bullet-proof.
