1. The problem statement, all variables and given/known data - Assume that 1 in 200 people carry the defective gene that causes inherited colon cancer. A sample of 1000 individuals is taken.

Use the Poisson approximation to calculate the appoximate standard deviation of the number of people who carry the gene.


2. Relevant equations



3. The attempt at a solution I am honestly having a hard time even getting started with this one. I think I find Lamda by setting 1-[tex]e^{-\lambda1000}[/tex]=1/2
