Rotation about the origin
So chance to get a black pen: 4/10=2/5
Chance to get a red pen: 1/10
Chance for the two happened at the same time
2/5 * 1/10 = 2/50=1/25
I think... I’m not very sure though
2 is greater then -5.
2 is a positive number unlike -5 it is a negative which is less then 2.
The 3rd one. (where the round part of the graph is at 0, 0) because that is where the y axis meets
X+y=6
x=10
10+y=6
y=-4
10=-4+z
-4+z=10
z=10+4
z=14
So the correct answer is 14
