An ice cream parlor sells 10 different varieties of ice cream and 3 different kinds of cones. (a) Mickey Mouse says there are 93 ways to get a two-scoop cone because there are 10 ways to select the first scoop, 9 ways to select the second scoop, and 3 options for the type of cone: 10 + 9 + 3 = 93. (b) Minnie Mouse says there are 300 ways to get a two-scoop cone because there are 10 ways to select the first scoop, 10 ways to select the second scoop, and 3 options for the type of cone: 10 × 10 + 3 = 300. (c) Donald Duck says that there are 150 ways to get a two-scoop cone because there are 10 ways to select the first scoop, 10 ways to select the second scoop, and 3 options for the type of cone, however you should divide by 2 because the order of the scoops doesn't matter: = 150. 10*10*3 2 (d) Daisy Duck says there are 270 ways to get a two-scoop cone because there are 10 ways to select the first scoop, 9 ways to select the second scoop, and 3 options for the type of cone: 10 * 9 * 3 = 270. (e) Goofy says there are 30 ways to get a double-scoop cone (two scoops of one flavor) and 270 ways to get a two-scoop cone where the flavors are different, therefore there are 300 ways to get any two-scoop cone: 30+ 270 = 300.
