expected-value-tb 0.0.1

A simple package which calculates the total probability and expected value of the outcome data type

Expected Value Package

This is a simple package which offers functions to calculate the expected value and the total probability for the outcome data type.

Importing

You can import the expected value package by:

from expected_value import expected_value

Using Expected Value

You can use the Expected Value command using:

o1 = outcome.Outcome("win", float(2), probability.Probability(.5))
o2 = outcome.Outcome("tie", float(10), probability.Probability(.1))
o3 = outcome.Outcome("lose", float(-1), probability.Probability(.4))

os = [o1, o2, o3]

print(expected_value(os))

which will output 1.6.

You can use the permutations (where order does matter) command using:

o1 = outcome.Outcome("win", float(2), probability.Probability(.5))
o2 = outcome.Outcome("tie", float(10), probability.Probability(.1))
o3 = outcome.Outcome("lose", float(-1), probability.Probability(.4))

os = [o1, o2, o3]

print(total_probability(os))

which will output 1.0.
