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.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
