A potato is launched into the air at a velocity of 60 feet per second off of a building that is 210 feet tall. This can be modeled by the formula h=-16t^(2)+60t+210, where h is the height (in feet) after t seconds. When will the potato hit the ground? (Round to the nearest second.)

In a board game, you must roll two 6-sided number cubes. You can only start the game if you roll a 1 on at least one of the number cubes. Make a list of all the different possible outcomes when two number cubes are rolled. (2 points for listing all of the possible outcomes) What fraction of the possible outcomes is favorable? (1 point for the correct numerator/1 point for the correct denominator) Suppose you rolled the two number cubes 100 times, would you expect at least one 1 more or less than 34 times? Explain. (1 point for your explanation)
