BUAL 2600 EXAM 3 – GUPTA QUESTIONS AND
ANSWERS 2026
To determine a Probability, we collect ____ from an Experiment to study the effects of a
change. - Answers - Data
DEF: A scientific process in order to make a discovery, test a hypothesis, or investigate
a known fact from historical data; Process that results in an outcome - Answers -
Experiment
DEF: A collection of independent Experiments - Answers - Trial
The Probability of an Event is always between ____ and ____. - Answers - 0 and 1
DEF: A number that measures
the likelihood that an Event will occur - Answers - Probability
A Probability that is greater than .70 is considered ____. - Answers - Good
A Probability that is less than .40 is considered ____. - Answers - Poor
A Probability that is between .40 and .70 is considered _______. - Answers - Average
DEF: Each Outcome from an Experiment - Answers - Event
DEF: A result from an Experiment that can be observed - Answers - Outcome
The closer the Probability is to 1, the ____ likely the Event will occur. - Answers - More
The closer the Probability is to 0, the ____ likely the Event will occur. - Answers - Less
DEF: Type of Event that occurs given that the first Event has already occurred -
Answers - Dependent Event
DEF: The set of all possible outcomes or Events for an Experiment - Answers - Sample
Space
The sum of the Probabilities of all the sample points within a Sample Space must equal
to ___. - Answers - 1
DEF: The identical and independent repetitions of an Experiment with two possible
outcomes; Categorizes a Random Variable having two possible Outcomes, each with a
constant Probability of occurrence - Answers - Bernoulli Trial (Distribution)
, What conditions must the Bernoulli Trial meet? - Answers - The Experiment (each Trial)
has only two possible outcomes, denoted generally as a success or failure; a have or
have not
The Trials are independent, meaning the outcome of one Trial is independent or does
not affect the outcome of the other Trials
The Probability of a success remains the same from Trial to Trial
DEF: The Probability that one Event will happen under the condition that some other
Event is already known to have occurred - Answers - Conditional Probability
DEF: A numerical description of the outcome of an Experiment - Answers - Random
Variable
DEF: A Random Variable that can take one of a finite number of distinct outcome; A
variable in which the number of possible outcomes can be counted; Assumes a
countable number of values - Answers - Discrete Random Variable
DEF: A type of Distribution that has two possible outcomes and in which the probability
of success or failure are the same for each Trial; Can be thought of as simply the
Probability of a SUCCESS or FAILURE outcome in an Experiment or survey that is
repeated multiple times - Answers - Binomial Distribution
DEF: The number of successes that occur in a period of time or an interval of space in a
Poisson Experiment - Answers - Poisson Random Variable
DEF: Type of distribution used to determine the Probability a specific Event will occur
over a specified interval of time - Answers - Poisson Distribution
What does the Poisson Distribution model? - Answers - Models the number of
occurrences in some unit of measure
In a Poisson Distribution, how many Outcomes does the experiment have? - Answers -
two possible outcomes, success or failure
T/F: In a Poisson Distribution, the probability of success in a given interval must be the
same for all equal-size intervals of time or space. - Answers - True
In a Poisson Distribution, the number of successes in an interval is __________
(Independent/Dependent) of the number of successes in other intervals. - Answers -
Independent
T/F: In a Binomial Distribution, a set number of Trials are performed. - Answers - True
In a Binomial Distribution, how many Outcomes does the experiment have? - Answers -
Two outcomes, success or failure
