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:
380 different ways
Step-by-step explanation:
We can solve this problem using a permutation formula, as the order in a group of two students matter.
So, for this problem, we have 20 students and want to form groups of 2, so we have a permutation of 20 choose 2:
P(20,2) = 20! / (20-2)! = 20! / 18! = 20 * 19 = 380 different ways
Another way to solve this problem is:
For the first student being chose, we have 20 students available, and for the second student, we have just 19, as one was already chose, so the number of ways to choose these two students is 20 * 19 = 380
Answer:
The statement is True!
Step-by-step explanation:
Clare paid full price for an item.
Let Price of the item = x
Han bought the same item for 80% of the full price.
Han bought it for 0.8x
Clare said, I cants believe I paid 125% of what you paid, Han!
The above statement is True if;
125% of 0.8x = x
1.25 * 0.8x = x
x =x
The statement is True!
