Answer:
In parametric form:
Step-by-step explanation:
We first find the mid point:
Then, a vector parallel to the z-axis is:
Then remember the equation of a line passing through point and parallel to the vector
is:
So, in this problem we get:
After combining the two vectors:
In parametric form:
Answer:
66.67% probability that all selected components function properly
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the components are chosen is not important. So we use the combinations formula 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.
In this question:
Desired outcomes:
2 components which function properly, from a set of 5. So
Total outcomes:
2 components, from a set of 6. So
Probability:
66.67% probability that all selected components function properly
