Urn 1 contains 5 white balls and 7 black balls. Urn 2 contains 3 whites and 12 black. A fair coin is flipped; if it is Heads, a ball is drawn from Urn 1, and if it is Tails, a ball is drawn from Urn 2. Suppose that this experiment is done and you learn that a white ball was selected. What is the probability that this ball was in fact taken from Urn 2? (i.e., that the coin flip was Tails)

The chamber of commerce for a summer resort is trying to determine how many tourists will be visiting each season over the coming years. A marketing research firm has estimated that the number of tourist can be predicted by the equation p = 276, 000 + 7500t, where p = the number of tourists per year, and t = years (measured from this current season). Thus, t = Oidentifies the current season, t = 1 is the next season, etc. if p is plotted on the vertical axis : a. Graph the equation b. Identify the slope and y intercept (p intercept, here) c.
