# Simulation of random numbers using STATDISK

Probabilities through Simulations

1)Dice Simulation - Use Statdisk to simulate 1000 rolls of a pair of dice. Sort the results, then find the number of times that the total was exactly 7. ___________.

Based on that result, estimate the probability of getting a 7 when two dice are rolled._____________.

How does this estimated probability compare to the theoretical probability of 0.167?_________________________________________________________.

Be sure to identify random seed when you activate dice generator.__________

2)Birthdays - Stimulate a class of 25 birth dates by randomly generating 25 integers between 1 and 365. Arrange the birth dates in ascending order, then examine the list to determine whether at least two birth dates are the same. (Use Uniform Generator)

Generated birth dates ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___
___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___
___
Are at least two of the birth dates the same?______________

3)Normally Distributed Heights - Stimulate 1000 heights of adult women. (Adult women have normally distributed heights with a mean of 63.6 in. and a standard deviation of 2.5 in.) Arrange the data in ascending order, then examine the results and estimate the probability of a random selected woman having a height between 64.5 in. and 72 in. (Those were the height restrictions for women to fit in Russian Soyuz spacecraft when NASA and Russia ran joint missions.) Enter the estimated probability _____________________________________.
