The probability of getting exactly 4 green marbles and 3 red marbles will be 0.19 WebThe termine whether the normal distribution can be used to estimate this probe result with the exact probability. n = 60, p = 0.2, and x = 20 P (X) = 0.0058 (Round to four decimal places as needed.) Can the normal distribution be used to approximate this probability? A. No, the normal distribution cannot be used because n p (1 − p) ≥ 10. B.
WebWe can calculate the exact probability using the binomial table in the back of the book with n = 10 and p = 1 2. Doing so, we get: P ( Y = 5) = P ( Y ≤ 5) − P ( Y ≤ 4) = 0.6230 − 0.3770 = 0.2460.
