sympy.stats.FiniteRV() function in Python
With the help of sympy.stats.FiniteRV()
method, we can create a random variable gives a dictionary of density by using sympy.stats.FiniteRV()
method.
Syntax :
sympy.stats.FiniteRV(name, dict)
Return : Return the variable having dictionary of density.
Example #1 :
In this example, we can see that by using sympy.stats.FiniteRV()
method, we are able to create the random variable which denotes the dictionary of densities by using this method.
# Import sympy and FiniteRV from sympy.stats import FiniteRV, P, E # Using sympy.stats.FiniteRV() method density = { 0 : . 1 , 1 : . 2 , 2 : . 3 , 3 : . 4 } X = FiniteRV( 'X' , density) print (E(X)) gfg = P(X > 2 ) print (gfg) |
Output :
2.00000000000000 0.40000000000000
Example #2 :
# Import sympy and FiniteRV from sympy.stats import FiniteRV, P, E # Using sympy.stats.FiniteRV() method density = { 0 : . 11 , 1 : . 20 , 2 : . 13 , 3 : . 4 , 4 : 0.16 } X = FiniteRV( 'X' , density) print (E(X)) gfg = P(X > = 3 ) print (gfg) |
Output :
2.30000000000000 0.56000000000000
