    We've just begun chapter 5 (Edexcel) and there are two questions that I'm stuck on:

    5. If S and T are two events and P(T) = 0.4, P(S n T) = 0.15 and P(S' n T') = 0.5, find:

    a. P(S n T')

    b. P(S)

    c. P(S u T)

    d. P(S' n T)

    e. P(S' u T')

    6. The events M and N are such that P(M) = P(N) = 2P(M n N). Given that P(M u N) = 0.6, find:

    a. P(M n N)

    b. P(M)

    c. P(M' n N')

    d. P(M n N')

    Thank you!

    I know, I've done the other seven questions, but I'm just stuck on those two.

    I tried to do the questions myself and got completely the wrong answers. It must be that I don't understand how to use the pieces of information given in the question properly.

    Post your working then and we'll point out what goes wrong. We can't do them for you.

    This, draw a frecking Venn diagram. It'll all become quite clear.
