For K=2:
For K=3:
For K=4:
Step-by-step explanation:
Fifth Root is given by:
The above equation will become:
It can be written as:
|z|=1,
According to De-moivre's Theorem:
Now, Fifth Roots of unity in standard form a + bi :
k=0,1,2,3,4
For K=0
For K=1:
For K=2:
For K=3:
For K=4:
if events X and Y are independent, then for intersection we multiply the probability
P(Y∩X) = P(Y) * P(X)
We know that
Now we replace P(Y) * P(X) for P(Y∩X)
Cancel out P(X)
So
Like that
Now we replace P(X) * P(Y) for P(X∩Y)
Cancel out P(Y)
So
P(Y | X) = P(Y) and P(X | Y) = P(X) are true
