esearchers have determined that children under 2 years old who sleep with the lights on have a 36% chance of becoming myopic (bad eyesight) before they are 16 years old. Children who sleep in darkness have a 21% chance of becoming myopic. A survey indicates that 28% of children under 2 years old sleep with some light on. Find the probability that a child under 16 years old is myopic.

According to the Center for Disease Control (CDC), the percentage of boys who are diagnosed with autism by the age of 8 is 2.7%. If 150 boys under the age of 8 are randomly selected, find the probability that the average of them being diagnosed with autism is more than 2.5%.

A drug test correctly gives a positive result 88 percent of the time. However, 3 percent of the time, it incorrectly gives a positive result. This is known as a false positive. Suppose that 5 percent of the people to be tested will have one or more of the drugs being tested for in their system. What is the probability that a randomly chosen person will have get a positive test result? Your answer should be to 4 decimal places.

According to the Turkish Ministry of Health, the probability of a woman developing breast cancer over a lifetime period is 1/5. What is the probability that 3 women out of 15 will develop breast cancer over a lifetime?

A software engineer receives a notification anytime a customer sends a crash report. Suppose the software crashes 2% of the time and there are 80 customers who use the software daily. What is the probability that the software engineer receives zero crash reports on any given day?

Radio frequency identification​ (RFID) is an electronic scanning technology that can be used to identify items in a number of ways. One advantage of RFID is that it can eliminate the need to manually count​ inventory, which can help improve inventory management. The technology is not​ infallible, however, and sometimes errors occur when items are scanned. The probability that a scanning error occurs is 0.0069. 1. Find the probability that the number of items scanned incorrectly is between 16 and 20 ​, ​inclusive, from the next 5100 items scanned. *Kindly explain the procedure in Excel for this* A) The probability is (Round to four decimal places as​ needed.) 2. Find the expected number of items incorrectly from the next 5100 items B) The probability is (Round to four decimal places as​ needed.)

A blood test indicates the presence of a particular disease 98​% of the time when the disease is actually present. The same test indicates the presence of the disease 0.5​% of the time when the disease is not present. One percent of the population actually has the disease. Calculate the probability that a person has the​ disease, given that the test indicates the presence of the disease.
