... The random variable X is approximately Binomial, with n = 25 and probability of success p = P [CEO is aware of information superhighway] = .5. Using Table 1 from the textbook, for n= 25, we get: a. P [X = 25] = P [X ≤ 25] – P [X < 25] = P [X ≤ 25] - P [X ≤ 24] = 1 – 1 = 0 b. P [X ≥ 10] = 1 – P [X ≤ ...
