Your first point would be on (0, 2), the vertex. Then, put a point on (-2, 22). Hope that helps!
64 is the answer and apparently it needs to be longer than 20 characters
12 out of 18. This is because there is 6 red marbles and 18 of them all together. The question states the probability of the red marble NOT being chosen therefore you need to take away 6 from 18 leaving you with 12. I hope this made sense :)
You would multiply 13/52 by 13/51 which you should receive an answer of 13/204
