Question:
If a sample of 2 hammer is selected
(a) find the probability that all in the sample are defective.
(b) find the probability that none in the sample are defective.
Answer:
a 
b 
Step-by-step explanation:
Given
--- hammers
--- selection
This will be treated as selection without replacement. So, 1 will be subtracted from subsequent probabilities
Solving (a): Probability that both selection are defective.
For two selections, the probability that all are defective is:




Solving (b): Probability that none are defective.
The probability that a selection is not defective is:

For two selections, the probability that all are not defective is:




Answer:
Option d (quantitative data) is the correct choice.
Step-by-step explanation:
- Quantitative data seems to be a collection or kind of data which is concerned regarding quantitative information or methods. That indicates its value, as well as the condition, could be represented arithmetically.
- All evidence that can be quantified, checked, and suitable for statistical analysis categorizes as quantitative methods.
The remaining three options do not apply to the specified scenario. Therefore the description made will serve as an example of quantitative data.
Answer: r=-7/6y+7/2
Step-by-step explanation:
Step 1: Add -5 to both sides.
6r+5+−5=−7y+26+−5
6r=−7y+21
Step 2: Divide both sides by 6.
6r/6=-7y+21/6
Answer:
This is achieved for the specific case when high quantum number with low resolution is present.
Step-by-step explanation:
In Quantum Mechanics, the probability density defines the region in which the likelihood of finding the particle is most.
Now for the particle in the box, the probability density is also dependent on resolution as well so for large quantum number with small resolution, the oscillations will be densely packed and thus indicating in the formation of a constant probability density throughout similar to that of classical approach.
