You are working in a test kitchen improving spaghetti sauce recipes. You have changed the ingredients in the sauce and have served it to 12 volunteers. You ask them if they like the new sauce or the old sauce better. You believe each individual person has a 80% chance of liking the new sauce better, but you also know there is a ringleader who is loudly praising the old sauce and the volunteers will follow his advice to varying degrees. So they don't all have the same 80% chance of liking the new sauce better. You want to know what the probability is that at least 9 out of your 12 volunteers will like the new sauce better. This probability can be modeled using A binomial random variable, with n = 12 trials and probability of success p = 0.80 A Poisson random variable with arrival rate 12 volunteers per evening An exponential random variable with lambda=0.80 A normally distributed random variable with a mean of 0.80 * 12 = 9.6 and a standard deviation yet to be measured None of these
