Raul's soccer team enters a tournament. He estimates that his team has a [tex]$50 \%$[/tex] chance of winning each of the three games they play. If they win all three games, they move to the championship. To model his team's chance of going to the championship, Raul performs a simulation using a coin.

- Let heads [tex]$(H)$[/tex] represent a win.
- Let tails [tex]$(T)$[/tex] represent a loss.

The results of the simulation were:

\begin{tabular}{|l|l|l|l|l|}
\hline
HTH & HHH & TTT & HTT & HHT \\
\hline
TTT & HTT & HTT & HTT & HHH \\
\hline
HHT & HTT & TTT & TTT & HTH \\
\hline
\end{tabular}

Which statement about the simulation is not true?



Answer :

To determine which statement about the simulation is not true, let's first analyze the results and calculations based on the provided data:

1. Simulation Results:
The simulation results are:
[tex]\[ \begin{array}{|l|l|l|l|l|} \hline HTH & HHH & TTT & HTT & HHT \\ \hline TTT & HTT & HTT & HTT & HHH \\ \hline HHT & HTT & TTT & TTT & HTH \\ \hline \end{array} \][/tex]

2. Count the number of times they win all three games:
Winning all three games is represented by "HHH".
We observe "HHH" in the simulation results, and it appears twice.

3. Count the total number of simulations:
We have a total of 15 simulation results.

4. Probability of winning all three games based on the simulation:
The number of simulations where the team wins all three games ("HHH") is [tex]\(2\)[/tex].
The total number of simulations is [tex]\(15\)[/tex].
Therefore, the probability of winning all three games based on the simulation is:
[tex]\[ \frac{2}{15} \approx 0.1333 \][/tex]

Given this information:
- Total occurrences of "HHH" (winning all three games) = 2
- Total number of simulations = 15
- Estimated probability of winning all three games = [tex]\(\frac{2}{15} \approx 0.1333\)[/tex]

Let's explore possible statements and identify which one is not true:

1. "The team won all three games in 2 out of 15 simulations."
This statement is true because we have observed "HHH" appearing 2 times out of 15.

2. "The total number of simulations conducted was 15."
This statement is true because there are a total of 15 simulation results.

3. "The probability of winning all three games, based on the simulation, is approximately 0.1333."
This statement is true because [tex]\(\frac{2}{15} \approx 0.1333\)[/tex].

4. "The team won all three games in 1 out of 15 simulations."
This statement is not true because the team actually won all three games in 2 out of 15 simulations.

Therefore, the statement that is not true is:

"The team won all three games in 1 out of 15 simulations."
