wgu stats module 7 probability
questions with correct detailed
answers
Qualitative Description= impossible
Quantitative Probability = 0% probability
Qualitative Description= Unlikely
Quantitative Probability = 1% to 30% probability
Qualitative Description= As likely as unlikely
Quantitative Probability = 40-60%
Qualitative Description= likely
Quantitative Probability = 70-99%
Qualitative Description= certain
Quantitative Probability = 100% - answer ✔✔-Examples of Quantitative and Qualitative
Probability
the procedure or situation in which the probability is being calculated
,example- rolling a dice, raining - answer ✔✔-experiment
the possibilities of what can occur during the experiment, the results
rolling a dice- 1,2,3,4,5,6 are outcomes - answer ✔✔-outcomes
comprised of 1 or more outcomes
die landing on an uneven number is an event - answer ✔✔-event
P(E)=
probability of a certain event occuring
if R= RAIN and the weatherman says there is a 40% chance of rain, then P(R)= .40 - answer ✔✔-
probability of an event
each outcome is equally likely - answer ✔✔-an experiment is fair if
False
Correct. This is a false statement. An experiment is the procedure for which the probability of an
event is calculated. - answer ✔✔-An experiment is the procedure to test the occurrence of an
event. True or False?
simply a collection of unique elements.
For example, a set of tree species is: oak, juniper, elm, maple. - answer ✔✔-set
, Set A is a subset* of set B , if every element in A is contained within B .
For example:
A={1,2,3}
B={1,2,3,4,5}
A is a subset of B , because every element in set A is contained within set B . - answer ✔✔-
subsets
has no elements
{}
For example, let's say you wanted to list the days of the week that do not end in a y. There are
none! Therefore, this is the empty set. In set notation, the empty set is written as a pair of
brackets with nothing between them: - answer ✔✔-empty set
The union* of two sets is a collection of all of the elements listed in the sets.
For example:
C={2,4,6}
D={1,3,5}
The union of C and D is {1,2,3,4,5,6} , as those are all of the elements that appear in the sets. -
answer ✔✔-union
The intersection* of two sets is a collection of the elements listed in both of the sets.
For example:
