Question
In a bag you have a total of 20 marbles, 10 blue, 3 red, 4 green and 3 yellow a. What is the probability you select a red marbles? b. What is the probability you select 2 blue marbles? (without replacement)? c. What is the probability you select a yellow marbles? Determine if the following full is the conditions for a binomial distribution H it is more binomial explain why. a. A fisherman fishing will continues to fish until he catches a rainbow trout. b. we flip a coin 3 time and observe the number of heads. c. A market researcher of a shopping mall is asking consumers whether they use detergent. She asks a sample of 4 men one of whom is clearly the employer of the other. d. The National Burglar and Fire Alarm Association reports that 34% of burgers get is through the does. A random sample of 3g burglaries is taken and the number of entries through the don't does is needed.Explanation / Answer
Q1 (a) P(red marble ) = 3/20
(b) P(2 blue marbles) = (10/20)*(9/19) = 9/38
(c) P(yellow or green ) = 7/20
Q2(a) No, It is not binomial distribution . It is geometric distribution
b) Yes, it is binomial distribution because each trial is independent and probability of sucess/failure is same in each trial
(c) No, it is not binomial distribution because each person opinion is different , so probability will not be same
(d) Yes, it is binomial distribution because each burglar entry is independent and probability of sucess/failure is same in each trial
