s1 help needed Desperately !!!!!!!!!!

Three events A, B and C are defined in the sample space S. The events A and B are mutually
exclusive and A and C are independent.
Given that P(A) = 0.2, P(B) = 0.4 and P(A or C) = 0.7, find
(b) P(AandC),
For two independent events A and C:

P(A∩C)=P(A)×P(C) P(A\cap C)=P(A)\times P(C)
and
P(A∩C)+P(A∪C)=P(A)+P(C) P(A\cap C)+P(A\cup C)= P(A)+P(C) (This holds for any two (not necessarily independent) events)

Hope this helps.

Ok, I will.



Sorry, I can't help. You haven't specified the year or session, and I do Edexcel.
