Answer:
0.4444
Step-by-step explanation:
Use the following property to ease the calculation:
P(At least one)=1-P(None)
Total number of electrical components: 9
Number that does not function well :1
Number that functions well : 8
We have ways to to choose 4 good components from 8.
We have ways to choose 4 components from a total of 9.
If all function properly then none is bad, we way to do this.
P(At least one)=
P(At least one)=
P(At least one)=0.4444
Answer:
The set of coefficients asociated with the given polynomial in ascending order is .
Step-by-step explanation:
Let , which is a polynomic function, defined as:
(1)
Where:
- i-th Coefficient.
- i-th Power.
- Grade of the polynomial.
We notice that given polynomial has degree 2 and can be rewritten by applying this definition:
Then, the set of coefficients asociated with the given polynomial in ascending order is:
