Answer:
4,210,000 - 6,315,000
Explanation:
Given that:
Percentage that suffer from lung cancer = 10-15%
Total population of smokers = 42.1 million
10% of 42,100,00 = 0.1 * 42,100,000 = 4210000
15% of 42,100,000 = 0.15 * 42,100,000 = 6315000
The range of the smoking population who will suffer from lung cancer is :
4,210,000 - 6,315,000
