Do the following conditional probability problems. At De Anza College, \(20 \%\) of the students take Finite Math, 30\% take History, and \(5 \%\) take both Finite Math and History. If a student is chosen at random, find the following conditional probabilities. a. He is taking Finite Math given that he is taking History. b. He is taking History assuming that he is taking Finite Math.
Do the following problems involving independence. If \(P(E)=.6, P(F)=.2,\) and \(E\) and \(F\) are independent, find \(P(E\) and \(F)\)
Jane is flying home for the Christmas holidays. She has to change planes twice on the way home. There is an \(80 \%\) chance that she will make the first connection, and a \(90 \%\) chance that she will make the second connection. If the two events are independent, find the following probabilities. a. \(P\) (Jane will make both connections) b. \(P(\) Jane will make at least one connection)
Consider a family of three children. Find the following probabilities. \(P\) (all girls | at least one girl is born)
Do the following problems using the conditional probability formula: \(P(A \mid B)=\frac{P(A \cap B)}{P(B)}\). If \(P(A)=.3\) and \(P(B)=.4,\) and \(P(A\) and \(B)=.12,\) find the following. a. \(P(A \mid B)\) b. \(P(B \mid A)\)
