    P(A and B')=P(A-B)

    I have no idea how to prove it. I only know B' means (1-B). But how this fit in that equation I'm in complete dark.

    What do you mean by A-B?

    Typically any proof of these things requires drawing a Venn diagram, labelling each of the areas and showing that the two sides of the equation refer to the equivalent area on the diagram...
