sympy.stats.Geometric() in Python

With the help of sympy.stats.Geometric() method, we can get a random variable which denotes the geometric distribution.

Syntax : sympy.stats.Geometric(name, P)
Where, P stands for probability
Return : Return the random variable of geometric distribution.

Example #1 :
In this example we can see that by using sympy.stats.Geometric() method, we are able to get the random variable which denotes the geometric distribution by using this method.

# Import sympy and geometric
from sympy.stats import Geometric, density, E, variance
from sympy import Symbol, S

p = S.One / 5

# Using sympy.stats.Geometric() method
X = Geometric("x", p)
gfg = density(X)(z)

print(variance(X))

Output :

20

Example #2 :

# Import sympy and geometric
from sympy.stats import Geometric, density, E, variance
from sympy import Symbol, S

# Using sympy.stats.Geometric() method
X = Geometric("x", 0.4)
gfg = density(X)(z)

print(variance(X))

Output :

3.75000000000000
