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.

Find the probability that a point is chosen randomly inside the rectangle is in each given shape...
BaLLatris [955]

Answer:

  1. <u>0.25</u>
  2. <u>0.85</u>

Step-by-step explanation:

P (Triangle or Square) :

  • 1/2 x 3 x 4 (height is found by Pythagorean Theorem) + (3)² / 10 x 6
  • 6 + 9 / 60
  • 15/60
  • <u>0.25</u>

P (Not the square) :

  • Area of rectangle - Area of square / Area of rectangle
  • 60 - 9 / 60
  • 51/60
  • 17/20
  • <u>0.85</u>
