BINOMIAL DISTRIBUTION CALCULATOR CHECK Open your calculator and enter the following values for each of the indicated BINOMIAL DISTRIBUTION variables: n 45 n-45 X 30 x - 30 p 0.6 P - 0.6 0.4 q, P(x) and I- P(x) will be calculated by q Excel. P(x) 8.19% Your calculator should look like this one. 1-P(X) 91.81% If you have any issues with the calculator, please contact your instructor immediately. Remember that to use the calculator, you have to enter the total number of trials (n), the specific number of trials out of n trials (x), and the probability of success (p) in decimal form. You will find all of these values in the problems. Instructions Use the Excel calculator provided to determine the probabilities. Write your answers EXACTLY as they are given to you in the calculator. Do not round. QUESTION 4.1 A certain gaming console company wants to estimate the lifetime rate of their newest console. The gaming company's in-house records showed that 80% of the older model consoles they had sold still worked after 3 years.

The probability that exactly 26 out of the 34 consoles are still working after 3 years is A Enter an answer . 3 points QUESTION 4.2 A test has 20 true/false questions. What is the probability that a student passes the test if they guess the answers? Passing means that the student needs to get 15 questions correct. (Hint: you must determine the probability of success; look at the number of choices of answers the student will select from) The probability that the student will get 15 correct questions in this test by guessing is A Enter an answer . 3 points
