Dan and Ella are paying $4 to play a game at the school carnival. Ella is blindfolded. Dan is given 7 coins to place in 2 different cups. He is given 4 pennies and 3 gold coins (identical in size). He randomly arranges them in the two cups in any combination he chooses. Ella is now instructed to choose a coin randomly out of one of the cups. If she chooses a gold coin, they win $20. If they choose a penny, they do not win anything. What is the probability that Ella will choose the gold coin in all possible situations ( I want a different probability for each situation)? Which combination would be BEST for Dan to choose when placing the coins in the cup? Which would be the worst?

TAKS reflection - 4th period
Reflect on the Math TAKS test you took yesterday.
How do you think you performed? What was the most difficult concept for you? Did you use any problem solving strategies (ie: guess and check, eliminating answer choices... etc.)? How much did you prepare yourself for this test? Did you study this past weekend? Is there anything you could have done differently to help you on this test?
