Answer:
535,095 different samples of size six that contain exactly 2 defective parts.
0.0337 = 3.37% probability that a sample contains exactly 2 defective parts.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
As the order of the parts is not important, the combinations formula is used to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
How many different samples are there of size six that contain exactly 2 defective parts?
2 defective from a set of 3, and 4 non-defective from a set of 47. So
535,095 different samples of size six that contain exactly 2 defective parts.
What is the probability that a sample contains exactly 2 defective parts?
The total number of samples is:
Then...
0.0337 = 3.37% probability that a sample contains exactly 2 defective parts.
Answer:
3rd option
Step-by-step explanation:
We first need to find the diameter of the circle.
We know this is a square because all sides are marked by a line so this means they are equal. Let find the diagonal of the square to find all parts of the square.
The diagonal of a square is
where a is the side lengths of the square.
So this means the diagonal of the square is
The diagonal is also the diameter of the main circle. The formula for circumference is
where d is the diameter.
So the diameter is
or
The third option is correct
