Decisionz was made to help people take decisions based on probabilities and expected values.
Comparing two choices, A and B, A in the top part of the screen. B in the bottom part.
Choose each probability and related value for the three levels (high chance, mediun chance and low chance), for both A and B situations.
For example, A has 5% and 500 as value, 80% and 1000 and 15% and -200
B has 30% and 1000, 30% and 10, 40% and -100
We caan see than A is better than B
Each time we change probabilities and values results are updated.
