The following table represents the hypertension and smoking habit of 180 individuals. Non Smokers Moderate Smokers Heavy Smokers

Hypertension 25 35 32

No Hypertension 44 27 17

One persons is picked at random from this group, find the probability that

i) The person is a heavy smoker

ii) The person is a non smokers given that the person has no hypertension

iii) The person is a moderate smokers given that the person has hypertension

iv) If two persons are picked at random calculate the probability that both are non smokers

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
