:3 Yes.

*I may have zoned out during these. xD
And I dun feel like thinking D: -
Alright. Post the problems. I'll walk you through them.
-
Mkay. So there are five gates A B and C on the left X and Y on the left. You can enter through X or Y and can exit through any of the five.
Blah Blah tree diagram of all possible ways to enter and exit..
Are all ways to exit and enter equally likely? -
X and Y on the right, I mean.
-
What? This is math? This is more like a thinking problem. So you have three entrances on the left and two on the right? Hm. This problem's really stupid. (No offence.) Are there any other clues or diagrams? I never learned about tree diagrams. I skipped Pre-Algebra and all that junk.
-
Yeah. It's probability.
Okay. I know the tree diagram, it's basically that out of all 5 (A B C X and Y) you can exit out of all. So there are 30 different ways to exit. -
*25 different ways to exit
-
Oh, I know the answer.
You list them like this:
Across the side of the paper, put A, B, and C, one under the other.
Make two little 'branches' coming out of each one.
Then, next to the branches, label one as X and one as Y. -
I know. I've already made the tree diagram.
-
DAMNIT YOU GUYS. IT BASICALLY ASKING "If there are 25 items, are they equally likely to get picked."

And meanwhile, Alana is working on Quadratics, Radical Functions, Trigonometric Functions, etc. o3o Oh yeah, I remember learning that back in grade school. It was quite fun. I just forgot how to do it because I never fully paid attention. xD

I LOVE HOW I CAN DO ALGEBRA AND MULTIPLY IMPODSIBLE FRACTION WHICH NO ONE IN MY CLASS CAN DO, BUT I CANNOT DO THIS.
