An industrial expert conducts a test in which a randomly selected worker in requested to perform a particular task three times in succession. Each time the task is performed successfully, the worker is awarded one point . An additional bouns point is awarded if the worker succeeds all three times, and there is a 5 point penalty for three successive failures. Find the probability distribution for the random variable x that measure's the worker's test score and calculate the expected value??
