Best ResponseYou've already chosen the best response.2\[ T  \mathcal P(T) \]Will give you \[ \{1, 2\} \]

Best ResponseYou've already chosen the best response.0Yeah and the other side is \(\{\emptyset, \{1\},\{2\}\}\)

Best ResponseYou've already chosen the best response.2Yet \[ \mathcal P(T)  T \]Will get you a bunch of sets.

Best ResponseYou've already chosen the best response.0My bad, you're right it has to be 7 elements.

Best ResponseYou've already chosen the best response.2\[ T = 3 \\ \mathcal P(T) = 2^{T} = 2^3 = 8 \]You only gonna be taking out \(\{1,2\}\) so it should be 7 elements.
