sympy.stats.Rademacher() function in Python

The Rademacher distribution is distribution of discrete probability when a random variable has a half probability of being +1 and half probability of being -1. With the help of sympy.stats.Rademacher() method, we can create the random variable having randemacher distribution by using sympy.stats.Rademacher() method.

Syntax : sympy.stats.Rademacher(name)

Return : Return the rademacher distribution.

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

# Import sympy and Rademacher
from sympy.stats import Rademacher, density


# Using sympy.stats.Rademacher() method
X = Rademacher('X')
gfg = density(X).dict

print(gfg)

Output :

{1: 1/2, -1: 1/2}

Example #2 :

# Import sympy and Rademacher
from sympy.stats import Rademacher, density, P


# Using sympy.stats.Rademacher() method
X = Rademacher('X')
gfg = density(X).dict

print(P(gfg >= 0))

Output :

1/2
