Please answer number 2. Show work!!
**Statistical Literacy** 1. **Statistical Literacy** List three methods of assigning probabilities. 2. **Statistical Literacy** Suppose a weather app says that the probability of rain today is 30%. What is the complement of the event “rain today”? What is the probability of the complement? 3. **Statistical Literacy** What is the probability of (a) an event **A** that is certain to occur? (b) an event **B** that is impossible? 4. **Statistical Literacy** What is the law of large numbers? If you were using the relative frequency of an event to estimate the probability of the event, would it be better to use 100 trials or 500 trials? Explain.
