Re: simulate the problem

Hi mizzyyy;

What language do you you program in? Do you understand pseudocode well enough to translate it?

Re: simulate the problem

Hi;

You must know how to program in order to run a simulation. Or you must do it by hand. Either way, you must have been taught either one.
So which is it?

Get a penny, a nickel and a dime. Also get a sheet of paper and a pen or pencil. Tell me when you are prepared.

Re: simulate the problem

Oh boy, I have not read the question right. I am sorry. Can you get your hands on a 6 sided die? From a game maybe?

Re: simulate the problem

See at the top where it says generate random numbers.?

Where it says columns, put 3
Where it says rows, put 20
Put in the next two 1 to 3.

Press do it and tell me what you get.

Re: simulate the problem

Copy the table and put it into your next post. Try to make sure that it is nice and lined up. We are half done!

Re: simulate the problem

Just hold on, everything is fine.

A,B, and C represent the 3 questions.

In each row if you have a 3 under the letter then that means that you guessed that question correctly.

Look at row #1. How many of the questions did you get right and which ones?

That is correct! How many did you get right in row #8?

Re: simulate the problem

You got the idea. Now count how many rows have exactly two threes in them.
