The Auditing and Attestation (AUD) part of the CPA exam has 72 multiple choice questions with 6 options each (a through f). Let G represents the correct guesses in the test, knowing that the accountant did not study well for the test.What is the P(G=25)? What is P(G≥38)? P(16<G≤35)? P(G≤30)? Create a Probability distribution for this problem         

In a group of 76 Infectious Disease Physicians, 12 believe that Mr. Trump should open the economy no later than May 1st. To show support for his views, Mr. Trump randomly selected 13 physicians to stand with him on the podium. Let O= physician that believe in opening the economy by May 1st. Find P(O<4), P(7<O<10), P(O>6) Create a probability distribution table (PDT) for this problem
