Decision Analysis

If:

P(high) = .3
P(low) = .7
P(favorable I high) = .9
P(unfavorable I low) = .6

then P(favorable) = ?

Re: Decision Analysis

P(favorable) = P(favorable | high) * P(high) + P(favorable | low) * P(low)

Re: Decision Analysis

P(favorable) = P(favorable | high) * P(high) + P(favorable | low) * P(low)

How do I obtain the P(Favorable I low) value?

You can get it from P(unfavorable | low). Think about what that means...
