Cohp 350 Quiz 3 Questions With Accurate
Answers
0 correct answer impossible
1 correct answer certain
A, B & C correct answer specific events
addition rule correct answer P(A or B) = P(A) + P(B)
Bernoulli Trial correct answer -binomial distribution
-only 2 outcomes
-probability stays same through trial
-# trials fixed
Binomial Distribution Requirements correct answer -procedure has fixed number
of trials
-trials must be independent
-each trial must have all outcomes classified into two categories
-probabilities must remain constant for each trial
complementary event correct answer the complement of event A, denoted by A
with a line over it, consists of all outcomes in which event A does not occur
, continuous correct answer all numbers (decimals) on continuum (measurement)
continuous probability distribution correct answer -Notation=pdf
-always a curve
-curve called probability density function
cumulative distribution function correct answer -area under curve used to
evaluate probability as area
-outcomes measured
-area = 1
dependent correct answer A + B are dependent if the occurrence of one does
affect the probability of the occurrence of the other
discrete correct answer whole numbers
disjoint correct answer aka mutually exclusive; ex = A&B cannot occur at the
same time
event correct answer any collection of results or outcomes of a procedure
expected value correct answer average value of the outcomes
F correct answer failure
