Suppose that a member of the US Senate is randomly selected. What is the probability that the senator is up for reelection in November 2014, knowing that this senator is a Republican? Conditional probability calculates P(A/B) = P(AANDB) / (PB) A: The number of Republican senators up for reelection in November 2014 is 13 B: The total number of Republican senators is 37 P(13/37) = P(13+37) / 37 P(0.3513) = P(50) / 37 P(0.3513) = 1.3513 This seems incorrect
