MULTIPLE CHOICE

Your company has to assemble a shipment for a client, out of a warehouse with N total items. Of those N, you know that T are defective. Your customer orders Q items. How would you calculate the probability that the customer gets S defective items? Which type of probability would you use to analyze this? Pick one of the following:

A_ Bayes Probability

B_ Uniform Distribution

C_ Exponential Distribution

D_Normal Distribution

E_ Combinatorics

F_Binomial Distuibution

Which probability is associated with "no memory" ? I.e. if something has lasted 5000 hours, it is just as likely to last another 5000 hours as a new item is?

Bayes Probability

Uniform Distribution

Exponential Distribution

Normal Distribution

binomial distribution

Combinatorics Probability

You have a bunch of independent events that all have the same probability. You wish to calculate the probability that some number of those independent events happen. What type of probability question is this?

Bayes Probability

Uniform Distribution

Exponential distribution

Normal Distribution

Binomial Distribution

Combinatorics Probability

A distribution we have used in class to model the lifespan of something. The nature is that the probability is characterized by just it's mean, and it starts high, and drops over time. (It isn't the only one in the world for lifespan, and would actually not be accurate for biological aging, or things that are not the same as they get older)

Bayes probability

Uniform distribution

exponential distribution

normal distribution

binomial distribution

combinatorics probability

Explanation / Answer

binomial

because of the binomial model of success falure

exponential distrubution as

p(x>t+s/x>s]=p(x>t)

binomial distribution

reason trivial

exponential distribution

life span is always exponential and positively skewed(which is given)
