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.

What is 2 12/13 as a decimal rounded to the nearest tenth
Delicious77 [7]

Here is you're answer:

First, you need to convert the mixed number into a improper fraction, then you have to convert the improper fraction into a decimal, then round to the nearest tenth.

  • 2\frac{12}{13}
  • 2\frac{12}{13} = \frac{38}{13}
  • Now convert into a decimal:
  • 13 \div 38 = 0.34210526315789
  • Find the tenth place value:
  • PV = 8
  • 8 > 5
  • = 0.34210526315780

Therefore you're answer is "0.34210526315780."

Hope this helps!
