- and how much is within 2 standard deviations of the mean.
- OK, finally a few probability questions.
- Explain what we mean by the following, and why :
the probability of A or B is P(A) + P(B).
What assumptions are being made? What does this notation mean?
- Explain what we mean by the following, and why :
the probability of A and B is P(A)* P(B).
Again, what assumptions are being made?
