Answer:
GT, GV, PT, PV, ET, and EV.
Step-by-step explanation:
Given that
The number of topics Travis has to chose from are 3 topics(G, P, E).
The number of ways Travis can study each topic are 2 ways(T, V).
Essentially, the number of combinations Travis is expected to be able to chose from is given as
The number of combinations = The number of topics * The number of ways
The number of combinations = 3 * 2
The number of combinations = 6
Therefore, the total possible combinations has to be
GT, GV, PT, PV, ET, and EV
