A 2018 Pew Research Center survey found that more Americans believe they could give up their televisions than could give up their cell phones.t Suppose that the following table represents the joint probabilities of Americans who could give up their television or cell phone.Could Give Up TelevisionNoYes0.320.190.51Could Give UpCell PhoneNo0.350.140.490.670.33(a) What is the probability that a person could give up their cell phone?(b) What is the probability that a person who could give up their cell phone could also give up television? (Round your answer to two decimal places.)(c) What is the probability that a person who could not give up their cell phone could give up television? (Round your answer to two decimal places.)(d) Is the probability a person could give up television higher if the person could not give up a cell phone or if the person could give up a cell phone?The probability a person could give up television if they could not give up a cell phone is Select- than the probability a person could give up television if they could give up a cell phone.

Students taking the Graduate Management Admissions Test (GMAT) were asked about their undergraduate major and intent to pursue their MBA as a full-time or part-time student. A summary of their responses follows. Use the information from the table to assign probabilities. What is the probability of selecting a student that it is part-time or Other major, or both. That is P(Part-time U Other)? (Enter your answer in decimals NOT percentages.)

An online customer service department estimates that about 15 percent of callers have to wait more than 8 minutes to have their calls answered by a person. The department conducted a simulation of 1,000 trials to estimate the probabilities that a certain number of callers out of the next 10 callers will have to wait more than 8 minutes to have their calls answered. The simulation is shown in the following histogram. Based on the simulation, what is the probability that at most 2 of the next 10 callers will have to wait more than 8 minutes to have their calls answered?
Your going to garden May 1st. In recent years, it has rained on average of 30% of the days you will be gardening.
