Jamie picks one things from each group to eat.
How many different breakfast combinations are there for James to eat?

To find the number of different breakfast combinations, we can simply multiply the number of options in each group.

There are 2 options for eggs (scrambled and fried), 3 options for bread (toast, roll, and bagel), and 3 options for juice (orange, grapefruit, and apple).

Therefore, the total number of different breakfast combinations for Jamie to eat is: 2 (options for eggs) x 3 (options for bread) x 3 (options for juice) = 18.

Therefore, there are 18 different breakfast combinations for Jamie to eat.
