NS Software Quality Service(NS SQS) has an agreement with Canada Communication(CC) for resolving the bugs in their software. As a part of the agreement,CC sends a “BUNDLE” of bugs to NS SQS every week. Even though each bundle may contain any number of bugs,the average number of bugs in each bundle is 8. If the bundle contains 5 or less bugs,it is called a Feather. If it contains more than 10 bugs,it is called Gold ad if contains 6 to 10 (both inclusive) it is called Copper.
1. WHAT IS THE PROBABILITY THAT A BUNDLE RECEIVED IN A PARTICULAR WEEK IS GOLD?

2.NS SQS receives $ 20,000 for resolving the bugs in feather. The corresponding payment for Copper and Gold are $ 25,000 and $ 30,000 resp. What is the average payment received by NS SQS per week?

There are 3 employees at work vying for 3 desks. 2 desks are good, the 3rd one is bad. The manager, Tara, writes down a number between 1-20, and turns that paper over. She asks each employee (Rocky, Haley, Kandice) to come up with a number in that interval; whoever guesses the number that is exact or closest to the Tara’s number will get 1st choice, and from that point on.

Keep in mind that each employee only has to “not lose,” or simply guess the 2nd closest number from the Tara’s number, not to guess the 1st closest number. The goal all each employee is ONLY to avoid the 3rd desk, or guessing the number farthest from the Tara’s number.

What number should Rocky guess if he is the 3rd one to guess a number, after knowing Haley’s and Kandice’s guesses?

If he’s the 1st one to guess?

If he’s the 2nd?

A company manager wants to hire 4 people from a group of 10 applicants, 4 men and 6 women, all of whom are equally qualified to fill the position. If he selects the four at random, what is the probability that
i. All four will be women
ii. At least two will be men?

Using a Nonstandard Normal Distribution. Assume that women's heights are normally distributed with a mean given by µ = 63.6 in. and a standard deviation given by σ = 2.5 in. (based on data from the National Health Survey). Draw a graph, and find the indicated probability or percentage.
