A student is working on a quiz containing 15 multiple choice
questions. The probability that the student gets correct answer for
a multiple choice question is ๐=0.3. Let ๐denote the total number
of correct answers.
(a)Determine approximately the value of probability ๐(๐=4)by
using the central limit theorem with the correction for
continuity.(10 marks)
(b)Compute the exact value of the probability๐(๐=4)without
applying the approximation. Compare it with the answer obtained in
Question 2(a).(5 marks)
