ns.Look at the Model Its. How is finding 14··40• 130 like solving 14··405 c···130?Why are both 45 and 46 reasonable predictions for the number of country songs played in 130 songs? When 40 songs were played, 30% were rock songs. Why should you not expect exactly 30% of the 130 songs played to be rock songs?How can you use data from an experiment to make a prediction about how often an event will happen in a future experiment with more or less trials?Can you use Luis’s results to predict how many times another person’s playlist will play country songs? Explain.Reflect Think about all the models and strategies you have discussed today. Describe how one of them helped you better understand how to make predictions using experimental probability. 1

Regular selling price (price before discount) 100%.

Price after trade discount of 15% is 85% of regular selling price..

Price after trade discount reduced to 10% is 90% of regular selling price.

By reducing the trade discount from 15% to 10% meant increasing the selling price by 5% of the selling price before applying the trade discount.
