T15 Suppose that 90% of drivers are "careful" and 10% are "reckless." Suppose further that a careful driver has a 0.2 probability of being in an accident in a given year, while for a reckless driver the probability is 0.4. What is the probability that a randomly selected driver will have an accident within a year? (Enter your answer to two decimal places.)

14. QUESTION: Consider the following experiment. You draw a square, of width 1 foot, on the floor. Inside the square, you inscribe a circle of diameter 1 foot. The circle will just fit inside the square. You then throw a dart at the square in such a way that it is equally likely to fall on any point of the square. What is the probability that the dart falls inside the circle? (Think about area!) How might this process be used to estimate the value of r?
Q3 Suppose that a chemical laboratory test to detect a certain disease has the following statistics, Let E= {event that the tested person has disease } K = {event that the test result is positive } It is known that P (K\E)= 0,95 and P(K\E)=0,003 and 0,2 percent of the population actually has the disease. What is the probability that a person has the disease given that the test result positive? Solve by Bayer's Rule. You calculate four decimal points.
