Students must show work to receive full credit. 1. Differentiate “Empirical Probability” and “Classical Probability”. 2. Define “Independent Events”, “Mutually Exclusive Events”, and “Collectively Exhaustive Events”. 3. Suppose there are 15 red marbles and 5 blue marbles in a box. (3.a) If an individual randomly selects two marbles without replacement, what is the probability that both marbles are red? (3.b) If an individual randomly selects two marbles with replacement, what is the probability that both marbles are red? 4. Solve...
