Suppose that there are / = 8,000 voters in the population, 20% of whom favor Jones. Identify the event favors Jones as a success S. It is evident that the probability of S on trial 1 is 0.20. Consider the event B that S occurs on the second trial. Then B can occur two ways: The first two trials are both successes or the first trial is a failure and the second is a success. Show that P(B) = 0.2. (Enter your probabilities as fractions. ) P(B) = P(SS) + P(FS) 1600 .2 x + 6400 .04 8000 8000 X .072 X What is P(B| the first trial is S)? (Enter your probability as a fraction.) P(B |the first trial is S) = 1/25 X Does this conditional probability differ markedly from P(B)? They are nowhere near close. They are very close
