Question

(a) An ice cream shop has vanilla, chocolate and strawberry flavors. You also have
the choice of a sugar cone or waffle cone. Draw a tree diagram to show the different
kinds of double dip cones you could order. (Double dip means two scoops.) Assume
that choosing chocolate and then vanilla is different than choosing vanilla and then
chocolate. (So, order matters.)
(b) If you must choose two different ice cream flavors for your double dip cone, how
many possible different cones could you order?

Answer 1

(b) 3P2 * 2 = 12
