Use the information below to answer the following question(s). In a survey, the rate of heavy smokers was reported as 270 per 10
Eddi Din [679]

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
