How are casinos making money if two people can walk in and come out with more money? Apply what you have learned about probability distributions in this lesson. Y made money during their first short trip to the casino. What is the probability that she will finish with more money than she started with?ĭ.
Y, joins him at the casino and she plays 3 games of roulette, betting $1 on red each time. If an individual plays three rounds of American roulette, what is the probability that he or she will win all three times?Ĭ. Z plays a third round and bets $1 on red, what is the probability that he will win a third time?ī. Note that this is American roulette with 38 slots: 18 red, 18 black, and 2 green.Ī. If you use Minitab Express, copy + paste your output along with an explanation.įor a table of roulette betting odds see. First, he bets $1 on red and he wins! Then, he bets $1 on red again and he wins again! Use this information to answer the following questions. Z is in a casino for the first time! He decides to play some American roulette. What is the probability that a student will get all 15 questions correct?ģ. What is the probability that a student will get exactly 9 questions correct? What is the probability that a student will get 9 or more questions correct?į. In order to pass, a student needs to get 9 or more questions correct. What is the standard deviation of the quiz scores?Į. What are the values of the parameters n and p?ĭ. The students don’t know any of the content and they randomly guess at every question. The instructor made a mistake and printed the quiz for a much more advanced class. Each question has 3 answer options: A, B, and C. Be sure to include all relevant output and clearly identify your answers by writing a sentence.Ī class is taking a multiple-choice quiz that consists of 15 questions. Use Minitab Express to answer the following set of questions. If you were to randomly select one student from this sample, what is the probability that he or she would speak more than one language?Ģ. Complete the cumulative probability row of the following table:į.
What proportion of students in this sample can speak exactly 3 languages?Į. Is number of languages spoken a discrete or continuous variable? Explain why.ī. Below is the probability distribution of their responses.
In Spring 2016 a sample of 523 Penn State World Campus STAT200 students were asked how many languages they can speak.
