The probability that neither of them is a heavy smoker is 0.53 or 53%
<h3>What is genetic probability?</h3>
Probability serves to mathematically estimate the possibility of events that happen by chance, that is, as a matter of luck.
In this case: 
Probability that selected one is heavy smoker is:
p=270/1000=0.27
Number of individuals selected  is 2 and We know that:
P(X=x)=nc_x(1-p)^{n-x}(p)^x
We need to prove that X=0:
P(X=0)=nc_0(1-0.27)^{2-0}(0.27)^0
P=0.5329
