Step-by-step explanation:
We can model this random variable as a Poisson distribution with parameter λ=1/500*2000=4.
The approximate distribution of the number who carry this gene in a sample of 2000 individuals is:
a) We can calculate that the approximate probability that between 4 and 9 (inclusive) as:
b) The approximate probability that at least 9 carry the gene is:
Answer:
The answer is b= - 5
Step-by-step explanation:
-96 = -6 ( 1 - 3b )
-6 ( 1 - 3b ) = -96
1 - 3b = 16
3b = 16 - 1 = 15
b= 15 : 3 = 5
