Remember that, for independent events, the probability that both occurr is the product of the individual probabilities.
a) Probability of being contacted: 78% = 0.78
Probaility of refusing: 1 - 22% = 1 -0.22 = 0.78
Combined probability: 0.78*0.78 = 0.6084
b) The probability of failing to contact or making contact and not geeting them to agree 1 - the probability of contacting and getting them to agree.
The probabilityof contacting and getting them to agree is 0.78*0.22 = 0.1716
The the answer to this question is 1 - 0.1716 = 0.8284

bear in mind that, though the square has two valid roots, one negative and one positive, the hypotenuse is just a radius distance, and therefore is never negative.
Since the problem is requiring us to use the loan repayment calculator and here is what the calculator gave:
Loan Balance: $25,506.00
Adjusted Loan Balance: $25,506.00
Loan Interest Rate: 6.80%
Loan Fees: 0.00%
Loan Term: 10 years
Minimum Payment: $0.00
Monthly Loan Payment: $293.52
Number of Payments: 120 months
Cumulative Payments: $35,223.07
Total Interest Paid: $9,717.07
It is projected that you will need an annual salary of a minimum $35,222.40 to be capable to have enough money to repay this loan. This approximation assumes that 10% of your gross monthly income will be keen to repaying your student loans. This resembles to a debt-to-income ratio of 0.7. If you use 15% of your gross monthly income to repay the loan, you will need an annual salary of only $23,481.60, but you may experience some financial difficulty. This corresponds to a debt-to-income ratio of 1.1.
3/7 or 3:7 because you tossed the dice 7 times and got an even number 3 of those times.
