Answer: Our required probability is 0.58.
Step-by-step explanation:
Since we have given that
Number of students worked in Nursing home = 11
Number of students worked in Tutoring center = 13
Number of students worked in Soup kitchen = 8
Number of students worked in Library = 18
Total number of students = 50
Since 3 students are selected from the club.
We need to find the probability that none of the three students volunteer at the soup kitchen.
So, Remaining students would be 50-8 = 42
So, probability that none of three students at the soup kitchen is given by

Hence, our required probability is 0.58.

Step-by-step explanation:
Consider the polynomial
4th power polynomial function has at most 4 zeros.
Integer zeros can be only among the divisors of 42:

Check them:

Thus,

Zeros are plotted in attached diagram.
Answer:
NPV, IRR, payback.
Step-by-step explanation:
The best worst decision technique involves the choice modelling. In terms of the overall usefulness in the capital budgeting decisions,
-- the decision rule that is best is the NPV
-- the decision rule that is worst is payback period
The NPV capital budgeting tool provides accurate results and it also assumes cash flow can be reinvested at a discount rate.
The IRR is the second best budgeting tool where it assumes that the cash flows can be reinvested at IRR.
And the worst is the payback where it does not take into account its time value of the money and so it does not yield the correct as well as accurate results.
Therefore, ranking the rules from best to worst is : NPV, IRR, payback.
