1.       1.1) 23°C

1.2) 14°C

1.3) There is an high prediction of rain (60%). It is cloudy and there will be a minimum temperature of 13°C (it is higher than the other days). There will be a maximum temperature of 26°C (it is also higher than the other days). The temperature is therefore not to hot or too cold (normal temperature).

Daar is ‘n hoë voorstelling van reën (60%). Dit is bewolk en daar sal ‘n minimum tempratuur van 13°C wees (wat reeds hoër is as die ander dae). Daar sal ‘n maksimum tempratuur wees van 26°C (dit is ook hoër as die ander dae). Die tempratuur is dus gemiddeld (nie te warm of te koud nie = redelik).

2.       The probability is less than 50% that makes it less likely to rain. Therefore the chance is small.

Die waarskynlikheid is minder as 50% wat dit dus ‘n lae kans gee van reën. Dus is die kans van reën laag.

3.       Yes, I would advise someone to take a rain jacket or a umbrella to work/school. The probability is higher than 50% that makes it more likely to rain. Therefore the chance is high.

Ja, ek sal iemand aanbeveel om ‘n reënjas en of ‘n sambreel werktoe/skooltoe te neem. Die waarskynlikheid is hoër as 5-% wat dit hoogs waarskynlik maak dat dit sal reën. Die kans is dus hoog tot reën.

4.       50% means that there will be an equal chance of it would happen. If it was a 50% chance of rain it will make it hard for people to decide what to wear. It makes it easier for people to know what to wear or not to wear if it is less or more than 50% chance of rain.

50% beteken dat daar ‘n gelyke kans sal wees dat dit sal gebeur. As dit 50% kans was om te reën, sal dit moeilik wees vir ‘n mens om te besluit wat om te dra. Dit maak dit dus makliker as die 50% voorspelling van reën hoër of laer is as 50%.

5.       We can only predict what the chance of rain might be, but it may still be differently than our prediction. A 100% means it will happen and we will not be certain that it will happen. We don’t have a guarantee that it will it will not rain a certain day.

Ons kan slegs voorspel wat die kans sal wees tot reën, maar daar is stteds ‘n kans dat ons voorspelling verkeerd sal wees. ‘n 100% voorspelling beteken dat ons doodseker is dit sal gebeur en dan sal dit so gebeur en in die geval is ons dus nie. Ons het nie ‘n waarborg dat dit sal reën nie.

6.       Children at the age of 18-25 years are a high risk for accidents to happen. They are more likely to drive fast or take chances while driving. Older people have more experience than the younger age groups. Because they are a high risk for accidents to happen, their car insurance is higher.

Leerders tussen die ouderdom van 18-25 is ‘n hoë risiko vir ongelukke op  die pad. Hulle is meer waarskynlik om vinnig te bestuur en om kanse te vat. Ouer mense het meer ervaring as die jonger mense. Omdat die jongmense ‘n hoë risiko is dat ongelukke sal gebeur, is hul karversekering hoër.

7.       A person that smokes has a bigger chance of developing cancer or heart diseases, than people that doesn’t smoke. Therefore smoke leads to illnesses and can have a negative influence on a person’s health. It doesn’t mean if you smoke that it will happen to you; there is a chance, no guarantee.

‘n Persoon wat rook het ‘n grootter kans om kanker of hartversaking te kry as ‘n persoon wat nie rook nie. Dus kan rook lei tot siektes en kan dit ‘n negatiewe invloed op ‘n persoon se gesondheid hê. Dit beteken nie dat dit met almal sal gebeur wat rook nie, maar daar is ‘n kans. Dit is nie gewaarborg nie.

8.       For every 10 persons that uses the tooth paste, there is a chance that there may be one persons who’s teeth will be black.

Vir elke 10 mense wat die tandepaste gebruik, is daar ‘n kans dat daar ten minste een persoon sal wees wat se tande swart sal word.

9.       9.1) P(pass) = 82/315 = 26%  

            W(deur) = 82/315 = 26%

 9.2) P(Fail) = 233/315 = 74% 

       W(druip) =  = 74%

 9.3) P(pass) = 26%  [26% x 420 = 109,2  109 people].

       W(deur) = 26%  [26% x 420 = 109,2  109 mense].

               

10.   10.1) P(Rash) = 18/250 = 7,2% 

             W(uitslag) =  = 7,2%

10.2.1) Yes, according to 10.1s’ answer. 

        Ja, volgens 10.1 se antwoord.

10.2.2) The 7% sound better and smaller than 18 people. They make the situation less personal.

Die 7% klink better en na ‘n kleiner getal as 18 mense. Hulle laat die situasie minder persoonlik.

10.2.3) x 100 = 7 people                                                       

           x 100 = 7 mense

10.2.4) It is only a prediction. There is no certainty that it will happen.

Dit is slegs ‘n voorstelling. Daar is geen waarborg dat dit sal gebeur nie.
