Answer:
The probability is 
Step-by-step explanation:
If she has n distinct password candidates and only one of which will successfully log her into a secure system, the probability that her first first successful login will be on her k-th try is:
If k=1
Because, in her first try she has n possibles options and just one give her a successful login.
If k=2
Because, in her first try she has n possibles options and n-1 that are not correct, then, she has n-1 possibles options and 1 of that give her a successful login.
If k=3
Because, in her first try she has n possibles options and n-1 that are not correct, then, she has n-1 possibles options and n-2 that are not correct and after that, she has n-2 possibles options and 1 give her a successful login.
Finally, no matter what is the value of k, the probability that her first successful login will be (exactly) on her k-th try is 1/n
The answer to your question is,
$3.84, you take $69.20 and divide it by 18 and there is your answer!

<em>Answer: </em>
<em>A = $7,350.00</em>
<em></em>
<em>Step-by-step explanation:</em>
<em>Equation:</em>
<em>A = P(1 + rt)</em>
<em>First, converting R percent to r a decimal</em>
<em>r = R/100 = 9%/100 = 0.09 per year.</em>
<em>Putting time into years for simplicity,</em>
<em>30 months / 12 months/year = 2.5 years.</em>
<em></em>
<em></em>
<em>Solving our equation:</em>
<em>A = 6000(1 + (0.09 × 2.5)) = 7350 </em>
<em>A = $7,350.00</em>
<em>The total amount accrued, principal plus interest, from simple interest on a principal of $6,000.00 at a rate of 9% per year for 2.5 years (30 months) is $7,350.00.</em>
<em>* Therefor, the answer is $7,350.00.</em>
<em>* Hopefully this helps:) Mark me the brainliest:)!!!</em>
