I swear, stats is going to be the death of me.
Suppose A is an event with probability 0.12 and B is an event with probability 0.51.
If A and B are mutually exclusive, determine the following probabilities:
P(AC or BC) =
If A and B are independent, determine the following probabilities:
P( AC or BC) =
meaning, NOT A, and NOT B
So for the first one, I thought it was 0.37 and 0.4312 for the second one, but apparently they are marking it wrong.
Formula should be
P(AC or BC) = 1 - P(A or B)
why is it telling me it's wronggggg.
I got the P(A or B) correct for both, but why is P(NOT A and NOT B) wrong?
I accidentally did something to get the no response, ignore that. D;
I can't get the P(Ac or Bc) questions though. :|
