If there is a 10% chance it will rain each day for the next week, what is the probability that it will rain at least once?

In any given year a factory has a 10% probability of having a serious accident about every how Nagy years might the factory expect to have an accident?

If a seed is planted, it has a 95% chance of growing into a healthy plant.If 12 seeds are planted, what is the probability that exactly 3 don't grow? Round your answer to three decimal places.

A certain disease has an incidence rate of 0.7%. If the false negative rate is 8% and the false positive rate is 4%, compute the probability that a person who tests positive actually has the disease.

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.)

The probability of relapse into alcoholism can be modeled with a discrete random variable with mean ? = 4 years. Find the probability that a person will not reoffend in the first 2 years.

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.

A certain disease has an incidence rate of 0.2%. If the false negative rate is 5% and the false positive rate is 1%, compute the probability that a person who tests positive actually has the disease.
