In mathematics, the variance is the way to check the difference between the actual value and any random input, i.e variance can be calculated as a squared difference of these two values. With the help of sympy.stats.variance()
method, we can calculate the value of variance by using this method.
Syntax : sympy.stats.variance(value)
Return : Return the value of variance.
Example #1 :
In this example we can see that by using sympy.stats.variance()
method, we are able to calculate the value of variance using this method.
from sympy.stats import P, variance, Die
X, Y = Die( 'X' , 5 ), Die( 'Y' , 3 )
gfg = variance(X + Y)
print (gfg)
|
Output :
8/3
Example #2 :
from sympy.stats import P, variance, Die
X, Y = Die( 'X' , 2 ), Die( 'Y' , 4 )
gfg = variance(X * Y)
print (gfg)
|
Output :
75/16
