The formula for variance is p (1-p) In our example, where you have to choose from an answer to a question from 4 options, the probability of getting one question right s 0.25. The mean of the distribution is 15*0.25 = 3.75. The variance is np (1-p) = 15 * 0.25 * (1–0.25) = 2.8125.

The pnorm function gives the Cumulative Distribution Function (CDF) of the Normal distribution in R, which is the probability that the variable X takes a value lower or equal to x.. The syntax of the function is the following: pnorm(q, mean = 0, sd = 1, lower.tail = TRUE, # If TRUE, probabilities are P(X <= x), or P(X > x) otherwise log.p = …
