STATISTIC AND PROBABILITY

Solve the following problems. Tables and graphs should be presented if needed.

1. I am an iphone supplier here in the Philippines. I am able to ship 20 iphones to small cellphone shops. However, at a random supply, 2 of these phones have technical issues. At a random sample of 2, find the probability distribution for the number of phones with technical issues. 2. Determine the number of probabilities of getting exactly 4 fives when a certain die is tossed 8 times. 3. What is the expected value when a die is rolled? 4. The probability that you will pass Differential Equation is 0.3. If you have 5 friends in your circle including you, what is the probability that at most 2 are accepted? 5. A cafe restaurant has an average of 20 cups of coffee sold per day. Determine the probability that the cafe will sell exactly 25 cups the next day
