The probability that a person passes a test, P, is .7. The probability of not passing, NP, is .3.
P (P) = .7 P (NP) = .3
The probability that you came to class, C, given that you passed is .9. NC is did not come to class. The probability that you did not pass given that you came to class is .3.
P (C / P) =.9 P(C / NP) =.1
Find the probability that you passed given that you came to class.

The probability that a student passes a class is p(P) = 0.57. The probability that a student studied for a class is p(S) = 0.54. The probability that a student passes a class given that he or she studied for the class is p(P / S) = 0.74. What is the probability that a student studied for the class, given that he or she passed the class (p(S / P))? Hint: Use Bayes' theorem. (Round your answer to two decimal...
