Round your answers to parts a) and b) to two decimal places. a) What is P(C) ? b) What is P(CIL) ? c) Are C and L independent events? No, because P(C) and P(C| L) are not equal. Yes, because P(C) and P(C| L) are equal. 5. The NIH is creating a test for the Flu virus. The incidence of a Flu is low, 3 percent in the general population. There is a trial version, but it sometimes misses the disease. The probability of a false negative is 13 percent. Similarly, someone who does not have the Flu, will sometimes get a positive reading. The probability of this is 30 percent. Fill in the tree diagram and ... Answer in percent to 2 decimal places.
