Dr. Howard wants to know the probability that his children will strike him with plastic swords on Halloween. He does not know this directly, but he can calculate it indirectly. He knows that this probability depends on what costume his children wear. If they dress as characters from Star Wars, the probability that Dr. Howard will be hit with swords is 92%. If they wear any other costume, the probability that Dr. Howard will be hit with swords is 20%. He also knows that the probability that his children will dress as Star Wars characters is 40%. Using the total probability rule, what is the probability that Dr. Howard will be hit with plastic swords on Halloween? Group of answer choices 0.87 0. 0.632 0.448 0.488
