Answer: A probability of 1 means the event is certain to happen. A probably of zero means the event is certain not to happen.
Step-by-step explanation:

the polygon is 15 sided.
Answer:
Step-by-step explanation:
$9.87
- <u>2.81</u>
$7.06 Jenny has left
If my above assumption is correct, we can easily find the area of the left side of the rectangle by finding the area of 3 things. The first is the area of the entire region.
At = (0.8)(1.0+1.4) = 1.92
Next we need the area of the circle. Which is pi*r^2, with r being height divided by two. (0.4)
C = 0.502
Finally we need to find the area of the rectangle left region. Which is basically the rectangle from the center of the circle region to the end of the left of the entire region. This is just (1.0)(0.8) = 0.8
Finally we can find the area of the light blue area by just subtracting half the area of the circle (dark blue) from the area we just calculated.
0.8 - (0.502 / 2) = 0.549
Now for the probability we do this area divided by total area.
0.549/1.92 = 0.285 or about 0.29 which is just 29%
CF = FG = GC because it is equilateral triangle
So
3x + 0.8 = 2x + 3
3x–2x = 3 – 0.8
X = 2.2
Putting this value to DE
IT IS ALSO A EQUILATERAL TRIANGLE
SO
5x + 4 = 5× 2.2 +4 =
11+4 = 15
All side will be 15 of triangle CD = DC = CE = 15
