Answer:
The probability of getting two or more defectives in a sample of 200 items
0.3233
Step-by-step explanation:
<u>step1</u>:-
The probability of getting 1 percentage defective items is
P(D) =
Given total number of items is n=200
use the Poisson approximation to the binomial distribution that is
λ=np=200(0.01)=2
by using Poisson distribution P(X=r)=
<u>Step2:-</u>
The probability of getting two or more defectives items
using Poisson distribution
on simplification, we get
by using calculator e^-2 value is 0.13533
after simplification
Final answer:-
The probability of getting two or more defectives in a sample of 200 items
0.3233
Answer:
4 x 1 = 4 x 3 = 12 = 4 x 3
Step-by-step explanation:
sorry I'm having trouble with this too
The question says that the line is parallel to the line above, so it is horizontal. When the line is horizontal it will be a 'Y=' Then, you take a look at the y axis and check to see what part of the axis the line is going through. Therefore, you can figure out that the awnser is C. I hope this explanation helps!
I wish I could help u with this one
