Best ResponseYou've already chosen the best response.0Think of this as the opposite of the question: "What is the probability of finding exactly 0 or exactly 1 broken cookie in a bag of cookies?"

Best ResponseYou've already chosen the best response.0The probability of getting zero broken cookies is the easiest to calculate because it is just the probability that a single cookie is whole raised to the power of the number of cookies. (disclaimer: we are assuming that cookies being broken are completely independent events which is a horrible horrible assumption if this were in real life since you can drop a bag of cookies and break half of them at once)

Best ResponseYou've already chosen the best response.0So, what is the probability of 0 broken cookies out of 36?

Best ResponseYou've already chosen the best response.0What about a bag of two cookies, what is the probability that both are not broken?

Best ResponseYou've already chosen the best response.0Okay, what about just one cookie, if the chance that it is broken is 0.03, what is the chance that it is not broken?

Best ResponseYou've already chosen the best response.0If a cookie is broken 3% of the time, what percent of the time is it not broken?

Best ResponseYou've already chosen the best response.0I can't give you the answer @iamabarbiegirl. I need your help to think about the probability of these events happening if we are going to get to a binomial process.

Best ResponseYou've already chosen the best response.0The chance of two independent events both happening is the product of their respective probabilities multiplied together. So if a cookie is whole, say 90% of the time, then two cookies are whole 90% * 90% of the time. 90% * 90% is equal to 81%. (on a calculator we might say 0.90*0.90)
