    Smile Or & And

    Dear Forum. I am having trouble figuring out why..Two of the most important words in the study of probability are OR and AND. Sometimes they arenít even used in the statement of a problem, but one of them at least is almost always there, wheter verbatum or not. Explain how they can help you figure out what you need to do. Give examples.

    Any feedback would be appreciated..

    Thanks , -AC-

    You are must give a more clear-cut formation of that question.
    Perhaps giving an exact example will help clarify the meaning.

    OR indicates that either of two cases may be true
    AND indicates that both cases may be true

    P(A or B) = P(a) +P(b) - P(a and b)

    This sounds like a direct quote from a home-work "concept" question!
