If E and F are two independent events, such that P (E ∩ F ) = 1/6 , P (E' ∩ F' ) = 1/3 and (P (E) − P (F ))(1 − P (F )) > 0, then derive the relation between P(E) and P(F).
1. Suppose that E and F are independent events such that Pr[E] = .3 and Pr[F] = .4.
(f) Calculate Pr[E|F](g) Calculate Pr[F|E]
Can you give a scenario for e and f please?

Let A and B be two events such that P(A) = 0.05 and P(A U B) = 0.49. i) Calculate P(B') if events A and B are independent. ii) Calculate P(B) if P(A|B) = 0.32. iii) Suppose that a third event, C, exists. Derive an expression for finding P(B) in terms of P(C), P(B|C') and P(B U C'). Assume that events A and C are mutually exclusive.arrow_forward1. Let B₁,..., B, be independent events. Show P(ÜBi) i=1 = 1. - 1 i=1 (1 - P(B;)).arrow_forwardShow that if X E x²(m) and Y E x²(n) are independent random variables, then (X/m)/(Y/n) E F(m, n).arrow_forward
