Given the following data (2, 5, 1, 0, 5, 0, 7, 2, 3) Calculate the 3rd quartile from your "data". What's the probability that a randomly selected number from your data is even? Consider the events A = "a randomly selected number from your data is even" and B = "a randomly selected number from your data is above the 3rd quartile". Are these events disjoint, independent, neither, or both? Show your work.
