Problem: In the past, the probabilities are 0.5, 0.2. 0.2 and 0.1 that the individual Income Tax Return forms of the employees of a certain form are filled out correctly, contained only errors favoring the taxpayer, contained only errors favoring the government, or contained both kinds of errors, respectively. A. What kind of distribution does X have? B. From the latest batch of submitted tax forms, a sample of 70 was randomly chosen. What is the probability that 30 forms were filled out correctly, 15 contained only errors favoring the taxpayer, 15 contained only errors favoring the government, and 10 contained both kinds of errors? C. From the latest batch of submitted tax forms. a sample of 70 was randomly chosen. What is the expected number of forms that will contain errors both favoring the taxpayer and the government? Round off to the nearest hundredths.
