Each time its rolled it has a 1/6 chance of rolling a two. Out of 50, it should come up as 2 about 8.33 percent of the time. That is the theoretical probability. However, it came up as two 10 of the 50 times, or 20 percent. The difference is about 11.67
For Symmetry About Y-Axis, let's try to replace x with −x, and check if the equations still equal:
-x - y² = 0
The equation changed, so there is no symmetry about Y-Axis.
For Symmetry About X-Axis, let's try to replace y with −y, and check if the equations still equal:
x - (-y)² = 0
x - y² = 0
The equation stayed the same, so there is a symmetry in X-Axis.
Lets try Origin Symmetry Replacing x with −x and y with −y:
-x - (-y)² = 0
-x - y² = 0
The equation changed, so there is no Origin Symmetry.
No. 7-2=5 and 2-7= -5. So 7-2= positive 5 and 2-7= negative 5.
