A psychic network received telephone calls last year from over 1.5 million people. A recent article attempts to shed some light onto the credibility of the psychic network.
 
  One of the psychic networks psychics agreed to take part in the following experiment. Five different cards are shuffled, and one is chosen at random. The psychic will then try to identify which card was drawn without seeing it. Assume that the experiment was repeated 45 times and that the results of any two experiments are independent of one another. If we assume that the psychic is a fake (i.e., they are merely guessing at the cards and have no psychic powers), how many of the 45 cards do we expect the psychic to guess correctly? A) 9 B) 8 C) 0 D) 5

Question 2

  A) -1.34 B) -1.39 C) -1.26 D) -1.45
