in a multiple-choice test,each item has four choices.
(a)tell how to simulate the correct guessing of the correct choice.
Decide in advance which of the numbers 1 to 4 is "correct".
If you are using a TI-83 or better, run randInt(1,4,10)
That will give you 10 randomly selected digits from the set
1,2,3,4.
If you had decided that "3" is a "correct" answer count the number
of threes in the stream of 10.
(b)carry out your simulation.what do you find for the experimental probability?
I got one "3" in my stream of 10 random digits so the probability is 1/10.
----------------------------
(c)compare your result to the theoretical probability.
This is binary because you either get the correct answer or you don't.
The probability of success is 1/4; the number of trials for me was 10.
The expected number of correct answers is (1/4)*10 or 2.5
