Homework Answers
The correct option is (e): 83.592%
Given that,
The total population of all age groups = 300+450+152= 902
Primary attack of a disease means that chances of the disease to be happen in any person, so susceptible population before the primary stage = 250+420+84= 754
So the percentage= (754 x 100)/902
=83.59%
Thanks.
