Here's how you can do the experiment (simulation). Since each question has four choices, numbered 1,2,3,4. Then take a coin and throw it twice to represent your answer guess, with HH=0 HT=1 TH=2 TT=3
Assume the correct answer is {1,1,1,1}, or any other set you decide to have. Repeat this 5 times to get the 5 answers, and record the "correct" answers.
This constitutes ONE trial. You can repeat the number of trials as you are required to do. If the number of trials is a large number, you are better off writing a computer program, using Java, Excel, Perl, C, Basic, or any other language of your choice.
first take how much you need and add how much you want to leave, so 2500+500=3000. Then delete 600 from 3000, which will give you $2400. divide $2400 by 50 which gives you 48. it will take 48 months to get enough money to purchase a car at $2500 and leave $500 in the account.
