Scarlett is practicing math fluency. She has 100 math operation flashcards with 42 addition problem cards,
56 subtraction cards, and 2 multiplication cards. Scarlett will time herself to see how fast she can solve the
problems on seven cards. She chooses her seven cards and they are all addition cards. Is choosing all
addition cards likely? Explain by running a simulation.

Part A: State the problem or question and assumptions.

Part B: Describe the process for one repetition, including possible outcomes, assigned representations, and
measured variables.

Part C: Use digits from a table of random digits or use your calculator to perform one repetition. Submit the
list of random digits and indicate those that represent addition cards.

Part D: Suppose there was one repetition when all seven cards were addition cards after 200 repetitions of
the simulation. State your conclusions from these results.
