WGU STATS MODULE 7- PROBABILITY QUESTIONS
WITH CORRECT ANSWERS.
Examples,of,Quantitative,and,Qualitative,Probability,,ANS,-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%
experiment,,ANS,-the,procedure,or,situation,in,which,the,probability,is,being,calculated
example-,rolling,a,dice,,raining
outcomes,,ANS,-the,possibilities,of,what,can,occur,during,the,experiment,,the,results
rolling,a,dice-,1,2,3,4,5,6,are,outcomes
event,,ANS,-comprised,of,1,or,more,outcomes
die,landing,on,an,uneven,number,is,an,event
probability,of,an,event,,ANS,-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
an,experiment,is,fair,if,,ANS,-each,outcome,is,equally,likely
An,experiment,is,the,procedure,to,test,the,occurrence,of,an,event.,True,or,False?,,ANS,-False
Correct.,This,is,a,false,statement.,An,experiment,is,the,procedure,for,which,the,probability,of,an,event,
is,calculated.
set,,ANS,-simply,a,collection,of,unique,elements.
For,example,,a,set,of,tree,species,is:,oak,,juniper,,elm,,maple.
subsets,,ANS,-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,.
empty,set,,ANS,-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!,T
herefore,,this,is,the,empty,set.,In,set,notation,,the,empty,set,is,written,as,a,pair,of,brackets,with,nothi
ng,between,them:
union,,ANS,-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.
intersection,,ANS,-The,intersection*,of,two,sets,is,a,collection,of,the,elements,listed,in,both,of,the,sets.
For,example:
E={0,10,100},
F={−2,−1,0,1,2},
The,intersection,of,E,and,F,is,{0},,,as,0,is,the,only,element,that,appears,in,both,sets.
theoretically,probability,,ANS,-
is,calculated,as,the,number,of,ways,one,particular,event,can,occur,in,a,random,experiment,,divided,by,
the,total,number,of,possible,outcomes:
if,bob,has,3,blue,suits,,1,red,and,1,orange,what,is,the,probability,he,will,randomly,pick,a,blue,suit?
3/5
Empirical,(Observational),Probability,,ANS,-
gathers,data,by,performing,multiple,experiments,,or,trials,,and,recording,the,results,each,time.,For,exa
mple,,to,have,a,better,idea,of,the,probability,that,a,team,will,win,a,particular,game,,we,naturally,exami
ne,what,other,games,it,has,won,and,against,which,teams.
relative,frequency,,ANS,-
how,often,the,event,occurs,in,the,series,of,trials,(or,experiments),relative,to,the,number,of,trials.
