# 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}
```
