If you get a wrong answer, read the pages listed in red. deck of 52 cards. What is the probability the first card is a diamond? = 0.2, find P(E F) = 0.6, find P(E F). (pp. 391-400) If E and F are two events and P(F) > 0, then P(E|F) = If E and F are events with P(F) = 5/13 and P(E|F) = 4/5, find P(E F). If E and F are two events and P(F) = 0.38, then P(E|F) = 0.46, find P(E F). If E and F are events with P(E F) = 1/3, P(E|F) = 1/2, and P(F|E) = 2/3, find P(E) P(F) If E and F are events with P(E|F) = 0.1, P(E|F) = 0.25, and P(F|E) = 0.125, find P(E) P(F)

Solution

As

P(E|F) = P(E n F) / P(F)

Thus,

P(E n F) = P(F) P(E|F) = 0.38*0.46 = 0.1748 [answer]
