Question- What is the difference of finding the number of outcomes vs finding the probability?
Answer- Probability is a mathematical way of calculating how likely an event is to occur. The number of favorable outcomes is the number of choices and the probability is found by comparing this to the total number of outcomes

Answer:
(-b/2a, b^2/(4*a) - b^2/2a + c)
Step-by-step explanation:
For a general parabola:
y = a*x^2 + b*x + c
We can write the vertex as:
(h, k)
The x-value of the vertex is the value of the axis of symmetry.
Then we have:
h = x = -b/2a
Now we need to find the y-value of the vertex.
To do that, we just replace the variable "x" by the x-value of the vertex in our equation, so we get:
k = y = a*(-b/2a)^2 + b*(-b/2a) + c
k = b^2/(4*a) - b^2/2a + c
Then the coordinates of the vertex are:
(h, k) = (-b/2a, b^2/(4*a) - b^2/2a + c)
Answer:
(0,-2)
Step-by-step explanation:
substitute in 0 for x
and solve for y
