I don't have any simulation otherwise i would have made the graph and uploaded it. So that i can ask you where i am making the mistake. The graph t...

Matt,

When you say there is half chance that b is positive or b is negative. I hope you mean the below in the diagram and same for a.

Mitch, Thanks for your reply. But i am not able to understand 1/4. As you have mentioned "it is 1/4 of the circle within the yellow region" . However, it is part of 1/4 of the circle i.e x of 1/4 of circle I am not clear about 1/4. I think you are talking about the sector. Can you please clarify. Sa...

Set T consists of all points (x,y) such that x^2+y^2=1.

Set T consists of all points (x,y) such that x^2+y^2=1. If point (a,b) is selected from set T at random, what is the probability that b>a+1?

A.1/4
B.1/3
C.1/2
D.3/5
E.2/3

OA is A

If k does not equal -1, 0 or 1, does the point of intersecti

If k does not equal -1, 0 or 1, does the point of intersection of line y=kx+b and line x=ky+b have a negative x-coordinate?

(1) kb>0
(2) k>1

OA is C

How this question can be solved graphically.

Out of 30 cans, 10 are recycled, and 20 are not recycled. Now our goal is to reduce the number of soda cans to half (10) tha...
