1. Eighty-five mall customers were randomly surveyed across the state to determine if the live
entertainment provided had increased the amount of money they spent. Can the probability be found by
using the binomial probability formula? Why or why not? (1 point) a. No. The trials are fixed, but the events are independent and the 5% guideline does not apply to this situation. b. Yes. The events are dependent; however, the 5% guideline can be applied to this situation. c. Yes. The outcomes can be classified into two categories: the trials are fixed, and the events are independent. d. No. The events are dependent. 2. A local community college determines the probability that a student will reenroll for a second year is
0.91. A representative surveys 100 random first-year students and asks them if they will be enrolling for
the next year. What is the probability that exactly 91 of them will enroll?

following reasons is needed to satisfy the requirements for a binomial distribution?
(1 point) aEach outcome is easily obtainable. bThe number of times you roll the die is greater than 1. cEach of the 100 outcomes can be placed in one of two categories of outcomes. dEach roll of the die has 2 equally likely outcomes. 4. A bag contains 40 jellybeans with 5 dierent
colors. Each color is equally represented. You are interested
in randomly drawing one jellybean at a time and checking the color before eating it. You want to know
how many red jelly beans you will pull out of the bag during the first 10 draws. Can the probability be
found by using the binomial probability formula? Why or why not?
(1 point) aYes. The trials are fixed and the probability of success remains the same for every trial. bNo. The events are dependent, and the 5% guideline cannot be applied to this situation. cNo. The trials are fixed, but the events are independent. dYes. The events are dependent; however, the 5% guideline can be applied to this situation. 5. You flip a coin 10 times. Knowing that the event satisfies the requirements for a binomial distribution,
find the probability that exactly 7 of the outcomes are heads.
(1 point) a. 0.120 b. 0.001 c.0.117 6. The probability of drawing a heart from a standard deck of cards is 0.25. You record the card you draw
and return the card before shuling
to ensure a binomial distribution. If you do this 20 times, what is the
probability that you will draw a heart 7 times?

probability by rolling the dice 12 times. What is the probability that exactly 2 of the rolls is a sum of 7?

returns the card to the deck, shules,
and repeats the experiment. He performs the experiments 30
times. Can the probability of drawing his favorite suit be found by using the binomial probability
formula? Why or why not?
(1 point) aYes. The events are dependent; however, the 5% guideline can be applied to this situation. bNo. The trials are fixed, but the probability of success changes for every trial. cNo. The probability of success remains the same for every trial, but the trials are not fixed. dYes. The outcomes can be classified into two categories, the trials are fixed, and the events are independent. 10. Assume that a procedure yields a binomial distribution with a trial that is repeated 5 times. Use the
binomial probability formula to find the p…
