Answer: 10

Step-by-step explanation:

Given : The American Lung Association stated that approximately 1 out of every 20 deaths in the US last year was from lung cancer.

Then, the proportion of death will be :_

[tex]p=\dfrac{1}{20}=0.05[/tex]

Now, If there are 200 students in a class,  then the expected number of persons die from lung cancer :-

[tex]p\times200\\\\=(0.050)\times200=10[/tex]

Hence, we expect the number of persons die from lung cancer =10
