<h2>Analytic View:</h2>
If and event can occur in A number of way and fail in B number of ways, then probability of its occurrence is:
![P(A)= \frac{A}{A+B}](https://tex.z-dn.net/?f=P%28A%29%3D%20%5Cfrac%7BA%7D%7BA%2BB%7D)
or probability of its failing is:
![P(B)=\frac{B}{A+B}](https://tex.z-dn.net/?f=P%28B%29%3D%5Cfrac%7BB%7D%7BA%2BB%7D)
<h3>Example:</h3>
Rolling a number smaller than 3 in a dice.
A= 2 (1,2)
B = 4 (3,4,5,6)
![P(A)= \frac{2}{2+4}=\frac{1}{3}](https://tex.z-dn.net/?f=P%28A%29%3D%20%5Cfrac%7B2%7D%7B2%2B4%7D%3D%5Cfrac%7B1%7D%7B3%7D)
<h2>Relative Frequency View:</h2>
Definition of Probability in terms of past performances (data). It can be taken as how often things happens divided by all outcomes.
<h3>Example:</h3>
A batter has 50 safe hits at 200 bats, which makes his batting average
which is the probability.
<h2>Subjective View:</h2>
When you define a probability due to personel beleif in the likelihood of an outcome. It involve no formal calculations and varies from person to person, depending on their past experience.
<h3>Example:</h3>
A person beleives that probability that the batter will hit safely in the next bat is 0.75
Answer:
The area is:
![2 {x}^{2}](https://tex.z-dn.net/?f=2%20%7Bx%7D%5E%7B2%7D%20)
Step-by-step explanation:
Area of this figure is simply the product of the base and the height, as it just happens to be a slanted or inclined rectangle.
Therefore:
![a = 2x (x) = 2 {x}^{2}](https://tex.z-dn.net/?f=a%20%3D%202x%20%28x%29%20%3D%202%20%7Bx%7D%5E%7B2%7D%20)
Answer:
CCCCCCCCCC
Step-by-step explanation:
15
5x-2y=9......(1)
6x+ky=4......(2)
slope of eqn i= -5/-2
=5/2
slope of eqn ii = -6/k
since the line are perpendicular
5/2 * -6/k = -1
-30= -2k
k=15
