Achromosome mutation believed to be linked with colorblindness is known to occur, on the average, once in every 10,000 births. if 20,000 babies are born this year in a certain city:
1. what is the probability that at least one will develop colorblindness?
2. what is the exact probability model that applies here?
3. approximate the probability that 2 or more babies will develop colorblindness, using the appropriate poisson model.

0.8647,0.5940

Step-by-step explanation:

Given that a chromosome mutation believed to be linked with colorblindness is known to occur, on the average, once in every 10,000 births.

Hence for a sample of 20000 babies we can take average as 2.

2) Since n is very large and p is small but np is finite Poisson model applies here.

1)  the probability that at least one will develop colorblindness

=

3)  the probability that 2 or more babies will develop colorblindness, using the appropriate Poisson model.

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

correct me if i'm wrong and if it is i'm truly sorry.
