Number of service industry workers who have been unemployed for 26+ weeks = 0.09 * 8 million = 720,000

Total number of workers in service and manufacturing industries = 18 million

P = \frac{720,000}{18,000,000} = 0.04

@vidishas99 is there any video where all the questions in DD session 3 HW is discussed?

Hi @gregmat / @vidishas99

So, in the above problem, going by the fundamental definition of probability as \frac{successful outcomes}{total outcomes} , can we arrive at the solution as \frac{9}{200} = 0.045 (9% → service industry workers unemployed for 26 weeks or more & 200% → Both manufacturing and service industry workers combined) ??

Thanks
