  • Probability question?

    In a city, 54 % are conservatives, 16 % are liberals and 30 % are independents. Records show that, in a particular election, 77 % of conservatives voted, 68 % of liberals voted and 84 % of independents voted. For each of the following questions, express any probability value as a fraction or a decimal with 10 places. 

    If a person from such a city is selected at random and it is learned that he/she voted, what is the probability that he/she is independent?

  • Math probability question? Please help!?

    A foreman for an injection-molding firm admits that on 55% of his shifts, he forgets to shut off the injection machine on his line. This causes the machine to overheat, increasing the probability that a defective molding will be produced during the early morning run from 3% to 15%. The plant manager randomly selects a molding from the early morning run and discovers it is defective. What is the probability that the foreman forgot to shut off the machine the previous night?
