Question
19) A certain system has two components. There are 6 different models of the fist 19) component and 11 different models of the second. Any first component can be paired with any second component. A salesman must select 2 of the first component and 3 of the second to take on a sales call. How many different sets of components can the salesman take? 20) On a TV game show, a contestant is shown 8 products from a grocery store and is asked 20) to choose the three least-expensive items in the set, and then correctly arrange these items in order of price. In how many ways can the contestant choose the three items? A) 6 B) 336 C) 6720 D) 56 lity that one person 21)_ will win both prizes if that person buys exactly 2 tickets. C) 1140 A) D) 380 480 190 22) A committee consist of 8 women and 11 men. Three members are chosen as officers. 22) What is the probability that all three officers are women? C) 0.1703 A) 0.0746 B) 0.01243 D) 0.0578 23) 23) The following distribution is not a probability distribution because 0 P) 0.24 0.17 -0.22 0.0 A) the probability values are not discrete. B) the probability values do not add to 1. C) values of the variable are negative. D) a probability is negative. 0.31 24) 24) Fill in the missing value so that the following table represents a probability distribution. Pr) 0.42 0.08? 0.05 A) 0.33 B) 0.45 C) 0.25 D) 0.26Explanation / Answer
19) 1st component total choices 6 & 2nd component total choices 11
Select 2 from 1st and 3 from 2nd So total ways are = 6C2 * 11C3
So ans = c) 6C2 * 11C3
20) The ways to slect 3 times and arrange them = 8P3 = 8!/(8-3)! = 8!/5! = 336
Ans = B)336
21) the prob = event/ possible combinations = 2C2/20C2 = 1/(20*19/2) = 1/190
So ans = D)190
22) It has to select 3 men from 19 people so the prob = 8C3/19C3 = 0.05779 = 0.0578
So ans = D)0.0578
As per chegg policy we are supposed to answer only 1 question but still I have gone ahead and answered 4.
Hope the above answer has helped you in understanding the proble. Please upvote the ans if it has really helped you. Good Luck!!
