An article reports that 1 in 500 people carry the defective gene that causes inherited colon cancer. In a sample of 1500 individuals, what is the approximate distribution of the number who carry this gene?

a. Use the Poisson approximation to calculate the approximate probability that between 5 and 9 (inclusive) carry the gene.
b. Use the Poisson approximation to calculate the approximate probability that at least 9 carry the gene.

i do not know the answer

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
