sympy.stats.Coin() in Python

  • Last Updated : 01 Jun, 2020

With the help of sympy.stats.Coin() method, we can create a fair or unfair coin by using sympy.stats.Coin() method. A fair coin have the probability of Half but we can’t tell for unfair coin.

Syntax : sympy.stats.Coin(name, value)

Parameters :
Name – It stands for the name of the coin.
Value – By default it take Half and can change by using Rational value smaller than 1.

Return : Return the fair or unfair coin.

Example #1 :
In this example, we can see that by using sympy.stats.Coin() method, we are able to get a fair or unfair coin by using this method.




# Import Sympy and Coin
from sympy.stats import Coin, density
from sympy import Rational
  
# Using sympy.Coin method
X = Coin('X')
gfg = density(X).dict
  
print(gfg)

Output :

{H: 1/2, T: 1/2}

Example #2 :




# Import Sympy and Coin
from sympy.stats import Coin, density
from sympy import Rational
  
# Using sympy.Coin method
X = Coin('X', Rational(3, 5))
gfg = density(X).dict
  
print(gfg)

Output :

{H: 3/5, T: 2/5}
