The quality control manager of Marilyn's Cookies is inspecting a batch of chocolate-chip cookies

First, we need to identify the distribution that best models the number of chip parts per cookie

Question

The quality control manager of Marilyn's Cookies is inspecting a batch of chocolate-chip cookies that has just been baked. If the production process is in control, the mean number of chip parts per cookie is 7.1. Complete parts (a) through (d). a. What is the probability that in any particular cookie being inspected fewer than five chip parts will be found? The probability that any particular cookie has fewer than five chip parts is . (Round to four decimal places as needed.) b. What is the probability that in any particular cookie being inspected exactly five chip parts will be found? The probability that any particular cookie has exactly five chip parts is . (Round to four decimal places as needed.) c. What is the probability that in any particular cookie being inspected five or more chip parts will be found? The probability that any particular cookie has five or more chip parts is . (Round to four decimal places as needed.) d. What is the probability that in any particular cookie being inspected either four or five chip parts will be found? The probability that any particular cookie has four or five chip parts is . (Round to four decimal places as needed.)
