- The variable \(X\) represents the number of students out of \(5\) who like basketball.
- We seek the probability that none of the \(5\) students like basketball, which corresponds to \(X = 0\).
- According to the provided table, the probability \(P(X = 0)\) is \(0\).
- The final probability is \(\boxed{0}\).
Explanation
- Analyze the problem and data
We are given a simulation of student preferences for basketball based on a spinning wheel. Numbers \(0-5\) represent a student who likes basketball (a probability of \(\frac{6}{10} = 0.6\) per selection), and numbers \(6-9\) represent a student who does not like basketball (a probability of \(\frac{4}{10} = 0.4\)). We are tasked with finding the probability that none of the \(5\) randomly selected students like basketball, which corresponds to the random variable \(X = 0\), where \(X\) is the number of students who like basketball.
- Locate the probability in the provided table
The problem provides a table representing the empirical probability distribution obtained from the simulation of \(500\) trials. By examining the table:
| \(X\) | \(0\) | \(1\) | \(2\) | \(3\) | \(4\) | \(5\) \) \(P(X)\) | \(0\) | \(0.07\) | \(0.21\) | \(0.38\) | \(0.24\) | \(0.1\) \) |
We look for the value of \(P(X)\) when \(X = 0\). This value represents the probability that none of the \(5\) students chosen like basketball. From the table, we can directly read that \(P(0) = 0\).
- Conclude the probability
Based on the simulation results provided in the table, the approximate probability that none of the \(5\) randomly selected students like basketball is \(0\). Although theoretical probability might suggest a small non-zero value, we are instructed to use the results of the given simulation as the basis for our answer. Thus, we conclude that the approximate probability is \(0\).
Examples
This type of problem helps students understand how empirical data from simulations can be used to estimate probabilities. For example, if a researcher wants to estimate the likelihood of a rare event in a population, they might perform many simulations. Even if the theoretical probability is small, the simulation might result in a zero count for rare events, providing a practical, albeit approximate, understanding of the event's frequency in a controlled experiment.
