Starting from the left, the sequence of flavours rolled is Vanilla-Chocolate-Strawberry-Mint Chocolate Chip-Vanilla-Vanilla-Chocolate-Chocolate. Comparing each customer's flavour to the one directly in front of them, we see that there are 3 pairs with the same flavour: the 2nd and 3rd customers both chose Vanilla, the 5th and 6th customers both chose Vanilla, and the 7th and 8th customers both chose Chocolate. Therefore, the answer is (C) 3.
