17 Chapter 6 Probability and Simulation
18 Probability Models Model One: Disjoint Event What is the probability than a flipped M & M will land M side up? S: { M side up, M side down} M up.56 M down.44
19 Probability Models Model Two: Non-Disjoint Event What is the probability than a randomly selected and flipped M & M will be orange and land M side up? S: {orange and M up, orange and M down, not orange and M up, not orange and M down} Orange.358 M up

21 Chapter 7 Random Variables
22 Random Variables Discrete Random Variables Number of times a flipped M & M lands M side up
23 Random Variables Continuous Random Variables Distribution of mass
24 Chapter 8 Binomial and Geometric Models
25 Chapter 8 Binomial Questions Theoretical 107 M and M s are contained within a M and M packet. The probability that one will pick a red M and M at random is What is the probability of getting at least 3 red M and M s with replacement in 10 trials?
26 Binomial Distribution The mean of this data set is red M and M s. The standard deviation is reds away from the mean. The variance is
27 Chapter 8: Actual Binomial Trial # # of red M and M s picked In a sample size of 10 Probability of choosing a red M and M in trial
28 Geometric Questions 107 M and M s are contained within a M and M packet. The probability that one will pick a red M and M at random is What is the probability of picking the first red M and M at random on the 2th trial with replacement?
29 Actual Geometric Distribution Trial # Red M and M picked 2nd (1=yes, 0=no) The actual probability of picking the first red M and M at random on the 2th trial with replacement is 0.05.
30 Chapter 9 Sampling Distributions
31 Chapter 9 Distribution of Colors in the population
32 Chapter 9 Distribution of Colors in the population
33 The mean of the sampling distribution of p-hat is p= as. By the rule of thumb #1, the population size is greater than 10 times the sample size of 10 M and M s, so the standard deviation of p-hat is = Rule of thumb #2 does not apply in this situation because np>10 or n(1-p)>10, therefore a normal approximation may not be used. Due to the low frequency of red M and M s in our population, it would not be possible for rule of thumb # 2 to apply.
