The probability that a graduate student being male is 0.25 and that being female is 0.75. The probability that a male student passes the course is 0.7 and that a female student does it is 0.80. A student selected at random is found to have completed the course. What is the probability that the student is (i) male and (ii) female?



Three members X, Y and Z of a private club have been nominated for the office of the president. The probability the Mr. X will be elected is 0.3, the probability that Mr. Y will be elected is 0.5, and the probability that Mr. Z will be elected is 0.2?Should Mr. X be elected, the probability for an increase in membership fee is 0.8? Should Y or Z be elected, the corresponding probability for an increase in fee is 0.2 and 0.3?If fee has been increased, what is the probability that (i) Mr. X was elected president of the club? (ii) Mr. Y was elected president of the club?

Guys pls redirect him to the existing threads on probability instead of answering the ques here.

There are many threads available on Probability in the Quant sections where the problem could be posted. Answering it here will elicit few responses n later on this thread will be as good as dead,lost in the thousands available here making it difficult to track the problem
