WebThe pnorm function. 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 = …

WebWe can use the binomial distribution table to find these probabilities, or we can use the binomial formula and add the probabilities manually: P (x < 5) = 0.0282 + 0.1211 + 0.2335 + 0.2668 + 0.2001 P (x < 5) = 0.8497 (rounded to 4 decimal places) Therefore, the probability that x is less than 5 is approximately 0.8497. WebIn order to solve this problem, we first need to understand what this distribution will look like. Remember that a standard normal distribution has the mean at the center, with a z-score of 0.
