A professor of a writing class has given her students to type a 200-word essay to be completed without using a spell-checking software. The table below summarizes the probability distribution of X, the number of non-word errors: x 0 1 2 3 4 P(X=x) 0.1 0.2 0.3 0.3 0.1 1. Is the random variable X discrete or continuous? [fill1] 2. What is the expected number of "non-word errors" in the essay? [fill2]
