Answer:
The picture just shows the beginning logic. We now know that we need to find a polygon with an interior angle that has a ratio of 1:3 with its exterior angle.
We can use this formula to find the number of sides of the polygon:
((n-2)×180)/n = 120
(n-2)×180 = 120n
180n - 360 = 120n
60n = 360
n = 6
We now know that the shape has 6 sides with 120 degree interior angles.
A shape with 6 sides is a hexagon.

Step-by-step explanation:
The coin is to be flipped 2000 times.
The probability of getting a head is 0.3.
It is given that, we need to get a head in between 575 and 618 times.
If we will get 575 heads then we will get (2000 - 575) tails.
Hence, if we take that we want to get n times head, then we will get (2000 - n) times tail.
The probability of not getting a head is (1 - 0.3) = 0.7.
The probability of getting n times head is .
The required probability is ∑ , where .

The conversion only gets tricky with the cubed labels. Keep in mind that cm^3 is cm*cm*cm, and that m^3 is m*m*m, AND that there are 100 cm in 1 meter. Here's how the conversion will look if we expand it to make it simple to understand:
. If we do all that multiplying and dividing, and all the crossing out of the labels that cancel, we get
. There you go!
