MAT205 Intro Survey of Mathematics

Week 1 Discussion

Suppose you’re on a game show, and you’re given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what’s behind the doors, opens another door, say No. 3, which has a goat. The host then says to you, “Do you want to pick door No. 2 instead of door No. 1?” Is it to your advantage to switch your choice?  Use what you have learned about probability so far to defend your choice.

Week 2 Discussion

Experimental Probability (Links to an external site.)

What is the theoretical probability of rolling a fair die and obtaining a 1?  If you roll a fair die 6 times, how many times would you expect, theoretically, of obtaining a 1?  What if you performed an experiment and rolled the die 6 times. Will you definitely obtain your theoretical answer? Why is experimental probability often different than theoretical probability?  What do you think you should expect if you increase the number of trials, that is, rolls of the die?  Why?

Week 3 Discussion

You and a friend are playing a game with a pair of six-sided dice.  To determine a winner, you each roll the dice and total them.  Your friend wins if the total is 5, 6, 7, or 8.  You win if the total is 2, 3, 4, 9, 10, 11, or 12.  Is this game fair?  Why or why not?  Use what you have learned about probability so far to defend your choice.

Week 6 Discussion

Assume that a population is normally distributed with a mean of 100 and a standard deviation of 15. Would it be unusual for the mean of a sample of 3 to be 115 or more? Why or why not?  Justify your answer.

Week 7 Discussion

A kidney stone treatment study found that treatment A had 81 out of 87 successful trials in small stone treatments and 234 out of 270 successful trials in large stone treatments. Treatment B had 234 out of 270 successful trials in small stone treatments and 55 out of 80 trials successful in large stone treatments. Overall which treatment had a better success rate and why?
