Answer:
The ratio of a circle's circumference to its diameter
In other words: all the way around a circle divided by all the way across it.
The symbol is π (pi)
No matter how large or small the circle, its circumference is always π times its diameter.
π = 3.14159265358979323846... (the digits go on forever without repeating)
A rough approximation is 22/7 (=3.1428571...), but that is not accurate.

There are 2 ways to solve this system: by elimination or by graphing. I will solve it by elimination. First will solve for x.

Now we will solve for y using what we got for x.

Solution:

Step-by-step explanation:
If we have a fair coin the probability of landing a head is 50%.
We can think the question as what is the probability of landing four tails and then a head. That is we needed at least 5 tries to get a head.

Since this events are independent we can write it as
