To state: The experimental probability of guessing the answers and getting a passing grade based on this simulation if a person needs at least 3 correct answers to earn a passing grade.
A person has to take a multiple-choice quiz and there are 4 choices for each question. The person doesn’t know the answer to the last 5 questions, so guess the answers. The simulation results are:
The experimental probability for these trials is about
Given information:
There are 24 a person has to take a multiple-choice quiz and there are 4 choices for each question. The person doesn’t know the answer to the last 5 questions, so guess the answers, he person needs at least 3 correct answers to earn a passing grade. The Simulation results are:
Explanation:
Consider the random table shown below:
In each group, there are 5 numbers, number 1 represents the correct answer and the remaining numbers represents the incorrect answer.
From the above table, it can be seen that the number of group is 28, so the number of trials of the simulation conducted is 28.
Read the digit from the random number table and find the group having minimum three in 28 trials.
Observe the above table. It is very clear that the total number of 1 in 28 trials is 3.
Now find the experimental probability by dividing the total number pair having minimum three 1(3) by the total number of trials.
Therefore, the experimental probability for these trials is about
