(03.05 LC) Scаrlett is prаcticing mаth fluency. She has 100 math оperatiоn flashcards with 42 additiоn 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. (2 points)Part B: Describe the process for one repetition, including possible outcomes, assigned representations, and measured variables. (3 points)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. (3 points)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. (2 points) (10 points)
