Sophia,

so we can either have 1 cheese+1fruit combo OR 2 cheeses and 2 fruits combo

6c1 x 2c1 + 6c2 x 2c2 = (6 x 2) + (15 x 1) = 27

AcB means how many different B can we select out of A

Hey Logitech,

In your equation above, can you explain how 6c2 x 2c2 = (15 x 1)? I am not familiar with AcB expressions. Thx!
