5.3 Independence and the Multiplication Rule1 Identify independent events.MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question.Provide an appropriate response.1) There are 30 chocolates in a box, all identically shaped. There are 11 filled with nuts, 10 filled with caramel,and 9 are solid chocolate. You randomly select one piece, eat it, and then select a second piece. Is this anexample of independence? Answer Yes or No.A) NoB) Yes2) Numbered disks are placed in a box and one disk is selected at random. There are 6 red disks numbered 1through 6, and 7 yellow disks numbered 7 through 13. In an experiment a disk is selected, the number andcolor noted, replaced, and then a second disk is selected. Is this an example of independence? Answer Yes orNo.A) YesB) No3) After completing an inventory of three warehouses, a golf club shaft manufacturer described its stock of 12, 246shafts with percentages given in the table. Is the event of selecting a shaft independent of the warehouse?Answer Yes or No.A) NoB) Yes4) Two events are if the occurrence if the occurrence of event E in a probability experimentdoes not affect the probability of event F in the same experiment.A) independentB) mutually exclusiveC) dependentD) disjoint5) Two events are if the occurrence of event E in a probability experiment changes theprobability of event F in the same experiment.A) dependentB) mutually exclusiveC) independentD) disjoint6) True or False: Mutually exclusive events are always independent.A) FalseB) True2 Use the Multiplication Rule for independent events.MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question.Solve the problem.7) Suppose that events E and F are independent, P(E) 0.7 and P(F ) 0.2.
