A high school has 438 students, with about the same number of males as females. Describe a simulation to predict how many of the first 50 students who leave school at the end of the day are female.
For a scavenger hunt, Chessa put one coin in each of 10 small boxes. Four coins are quarters, 4 are dimes, and 2 are nickels. How could you simulate choosing one box at random? Would you use the same simulation if you planned to put these coins in your pocket and choose one? Explain your reasoning.
About half of the 50 students are female.

To simulate the prediction of the number of females among the first 50 students who leave school at the end of the day, you can follow these steps:
1. Determine the ratio of males to females in the high school. Since the number of males and females is approximately the same, we can assume an equal distribution. Thus, there would be approximately 219 males and 219 females in the school.
2. Randomly select students from the student population. To simulate the departure of students at the end of the day, you need to randomly select 50 students from the total student population of 438. This can be done using a random number generator, ensuring that each student has an equal chance of being selected.
3. Count the number of females among the selected students. As you randomly select each student, keep track of whether they are male or female. Count the number of females among the selected 50 students.
4. Repeat the simulation multiple times. To get a more reliable prediction, repeat the simulation numerous times. Each repetition represents a different sample from the total student population.
5. Calculate the average number of females. After running the simulation multiple times, sum up the number of females and divide it by the number of simulations to find the average number of females among the first 50 students who leave school.
By following these steps, you can create a simulation that predicts the average number of females among the first 50 students who leave school at the end of the day based on the assumptions of an equal distribution of males and females in the school.
