Why is this not a valid probability measure? (Brisk · Chapter 1) — "I told you that Pr({Ben})=.1, Pr({Chad})=.2, Pr({Grover})=.3, and Pr({Tim})=.3. Would you b…
Ideas in this flowchart
- The listed values do not define a valid probability measure.
- The claimed probabilities are Pr({Ben}) = .1, Pr({Chad}) = .2, Pr({Grover}) = .3, and Pr({Tim}) = .3.
- The probabilities of all outcomes must sum to Pr(Ω) = 1.
- The claimed probabilities sum to .9.
- Because .9 is not equal to 1, the probability measure is invalid.
- The claim should not be believed.
