The One With でしょう。

"Probably":
Plain form + でしょう。

E.g.
今週私は勉強しないでしょう。
I will probably not study this week.

That is true.
But I have a midsem on Friday. :(
Also, I just spent a whole hour of Jap Lecture playing with Lucy's iPhone. So happy I beat Judy's score in that stupid falling balls game. WOOOOO :D
