Question

Rodney likes orange fruit punch. His mom buys it in a mixed pack of two orange, two grape, and two cherry. If Rodney reaches in the refrigerator and pulls out a punch without looking, about how many times will he get orange in 30 tries?

Answer 1

We cannot say with certainty how many times Rodney will get orange. 
Assuming that the packs are constantly replaced:

Orange constitutes 2/6, or 1/3, of a pack.
2/6 x 30 = 60/6 = 10 orange juice packs.
