MAT 122 Statistics Exam Questions and

Answers 100% Pass | Rated A+


Values that cannot be probabilities: -0.44, 1.45, sqrt2, 5/3 - ✔✔Which of the

following values cannot be probabilities?

0.03, -0.44, 5/3, 0, sqrt2, 1.54, 3/5, 1

P(A)=(number of ways A can occur)/(number of different simple

events)=s/n

50-12=38

(38)/(50)=0.76

The probability is: 0.76 - ✔✔Twelve of the 50 digital video recorders

(DVRs) in an inventory are known to be defective. What is the probability

you randomly select an item that is not defective?

If an event cannot occur then it has a probability of 0, and if it is certain to

occur then it has a probability of 1.

The probability is: 1 - ✔✔You are certain to get a number or a face card

when selecting cards from a shuffled deck. Express the indicated degree of

likelihood as a probability value between 0 and 1 inclusive.

,P(A)=(number of times A occurred)/(number of times the trial was

repeated)

14/500=0.028



Would it be unlikely for a driver in that age bracket to be involved in a car

crash this year?

Yes



Is the probability high enough to be of concern to those in the 20−24 age

bracket?

No - ✔✔Among 500 randomly selected drivers in the 20−24 age bracket,

14 were in a car crash in the last year. If a driver in that age bracket is

randomly selected, what is the approximate probability that he or she will

be in a car crash during the next year? Is it unlikely for a driver in that age

bracket to be involved in a car crash during a year? Is the resulting value

high enough to be of concern to those in the 20−24 age bracket? Consider

an event to be "unlikely" if its probability is less than or equal to 0.05.

The probability that a passenger prefers the middle seat is: 0.009.



Is it unlikely for a passenger to prefer the middle seat?

, Yes, because the probability that a passenger prefers the middle seat is

less than 0.05.



If so, why is the middle seat so unpopular?

The middle seat lacks an outside view, easy access to the aisle, and a

passenger in the middle seat has passengers on both sides instead of on

one side only. - ✔✔Among respondents asked which is their favorite seat

on a plane, 485 chose the window seat, 77 chose the middle seat, and 310

chose the aisle seat. What is the probability that a passenger prefers the

middle seat? Is it unlikely for a passenger to prefer the middle seat? If so,

why is the middle seat so unpopular?

a. What is the probability of exactly 2 girls out of three children?

3/8



b. What is the probability of exactly 3 girls out of three children?

1/8



c. What is the probability of exactly 1 boy out of three children?

3/8 - ✔✔To the right are the outcomes that are possible when a couple has

three children. Refer to that list, and find the probability of each event.
