Step-by-step explanation:
3x-x+2=4
Answer:
Step-by-step explanation:
Given expression is,

To prove this identity we will take the right side of the identity,


![=\frac{1}{2}[\frac{2(1-\text{tan}^2\frac{A}{2})}{2tan\frac{A}{2}}]](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B2%7D%5B%5Cfrac%7B2%281-%5Ctext%7Btan%7D%5E2%5Cfrac%7BA%7D%7B2%7D%29%7D%7B2tan%5Cfrac%7BA%7D%7B2%7D%7D%5D)
[Since
]
= cot A
Hence right side of the equation is equal to the left side of the equation.
Answer:
A. The probability of event A
Step-by-step explanation:
The proportion of times a particular event A occurs is known as the probability of event A because the probability is the measure of uncertainty and by definition probability is calculated as
P(x)=X/n
where
P(x) is the probability of occurring of random variable X
X=number of favorable outcomes
and
n= total number of outcomes.
Thus, the proportion of times a particular event A occurs is known as the probability of event A.
