Question

The Percentage of measurement that are above the 39th percentile is,A single die is rolled twice The set of36 equally likely outcomes l(1,1), (1,2), (1,3), (1,4). (1.5), (1.6), (2 2 3) (2 4), (2,5). (2 6), (3, 1), (3,2),(3,3). (3,4), (3.5), (3, 6), (4, 1). (4.2), (4,3), (4,4). (4.5), (4.6), (5, 1), (5,2), (5,3), (5,4), (5,5), (5,6), (6,1), (6,2), (6,3), (6,4), (6,5), (6,6)|. Find the probability of getting two numbers whose sum is greater than 3 and less than 6. Given that P(A or B) = 1/4, P(A) = 1/5, and P(A and B) = 1/9, find P(B). Find the area under the standard normal curve to the right of z = 1.5 You are taking a multiple-choice test that has 9 questions. Each of the questions has 3 choices, with one correct choice per question. If you select one of these options per question and leave nothing blank, in how many ways can you answer the questions?

Explanation / Answer

11.) 61%

12.) Sum greater than 3 and less than 6 = 4,5

Sum 4 = (1,3), (2,2), (3,1)

Sum 5 = (1,4), (2,3), (3,2), (4,1)

Total number of possible outcomes = 36

P(3 < SUM < 6) = 7/36

13.) P(A or B) = P(A) + P(B) - P(A and B)

0.25 = 0.2 + P(B) - 0.1111

P(B) = 0.1611 = 29/180

14.) Area = 1 - Area on left of z = 1.5

= 1 - 0.9332

= 0.0668

15.) Number of ways to answer each question = 3C1 = 3

Total number of questions = 9

Total number of ways to answer these questions = 9*3 = 27
