Uitkomste

Die uitkoms van ’n eksperiment is ’n enkele resultaat van daardie eksperiment.

  • ’n Moontlike uitkoms van Eksperiment 1: die waarde van die boonste vlak is ‘3’
  • ’n Moontlike uitkoms van Eksperiment 2: die totale waarde van die boonste vlakke is ‘9’

Steekproefruimte

Die steekproefruimte van ’n eksperiment is die volledige stel moontlike uitkomste van die eksperiment.

  • Eksperiment 1: die steekproefruimte is 1,2,3,4,5,6
  • Eksperiment 2: die steekproefruimte is 2,3,4,5,6,7,8,9,10,11,12

Interessante feit

Wanneer jy twee dobbelstene werp en die resultate sommeer, is die mees algemene uitkoms sewe. Om dit te verstaan, onthou dat daar net een manier bestaan waarop twee as ’n resultaat verkry kan word (beide stene land op een) en daar is slegs een manier om 12 as ’n resultaat te kry (beide stene land op ses). Die teenoorgestelde kante van ’n ses-kantige dobbelsteen sommeer na sewe. Van hierdie inligting moet jy kan uitredeneer dat daar 12 maniere bestaan waarop sewe verkry kan word.

Gebeurtenisse

’n Gebeurtenis is enige stel uitkomste van ’n eksperiment

  • ’n Moontlike gebeurtenis van Eksperiment 1: ’n ewe-nommer op die boonste vlak van die dobbelsteen
  • ’n Moontlike gebeurtenis van Eksperiment 2: die getalle op die boonste vlakke is gelyk

Ewekansige eksperimente

Die begrip ewekansige eksperiment of statistiese eksperiment word gebruik om enige herhaalbare proses te beskryf waarvan die resultate op een of ander manier ontleed is. Byvoorbeeld, die opskiet van ’n muntstuk en aantekening van die resultaat is ’n ewekansige eksperiment, want die proses is herhaalbaar. Aan die ander kant, jou lees van hierdie sin vir die eerste keer en aantekening van of jy dit verstaan of nie is nie ’n ewekansige eksperiment nie, omdat dit nie herhaalbaar is nie (indien jy wel ’n reeks verskeie mense vra om dit te lees en ’n aantekening te maak oor of hulle dit verstaan, al dan nie, sal dit ’n ewekansige eksperiment word).

Venn diagramme

’n Venn-diagram kan gebruik word om die verhouding tussen die moontlike uitkomste van ’n ewekansige eksperiment en die steekproefruimte te toon. Die Venn-diagram op [link] toon die verskil tussen die universele stel, ’n voorbeeldruimte en gebeure en hul uitkomste as deelversamelings van die steekproefruimte.

Diagram om die verskil tussen die universele stel en voorbeeldruimte uit te beeld. Die voorbeeldruimte bestaan uit alle moontlike uitkomste van ’n statistiese eksperiment en ’n gebeurtenis is 'n deelruimte van die voorbeeld ruimte.

Ons kan Venn-diagramme teken vir eksperimente met twee en drie gebeurtenisse. Hulle word gewys in [link] en [link] . Venn-diagramme vir eksperimente met meer as drie gebeurtenisse is meer kompleks en word nie op hierdie vlak behandel nie.

Interessante feit

Die Grieks-, Russiese- en Latynse-alfabet kan geïllustreer word deur middel van Venn-diagramme. Al drie hierdie alfabette het sommige gemene letters. Die Venn-diagram word hier onder gegee:

Die vereniging van A en B is die stel van alle elemente in A of in B (of in beide). A of B word ook geskryf as A B . Die snypunt van A en B is die stel van alle elemente in beide A én B . A en B word ook geskryf as A B .

In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,

What is different between quantity demand and demand?
Shukri Reply
Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded
