A television manufacturer sold three times as many televisions in 1995 as it did in 1985. To illustrate this fact, the manufacturer draws a pictogram as shown below. The television on the right is three times as tall and three times as wide as the television on the left. 000 1995 O ● 2005 This pictogram is misleading because it actually gives the visual impression that nine times as many televisions were sold in 2005 as in 1995. How can the manufacturer correctly illustrate the fact that sales in 2005 were three times sales in 1995?

Many say that baseball, which is commonly called America's National pastime, is a game with a low success rate. Consider Mookie Betts, one of the greatest players the sport has ever seen. He had a batting average (BA) of .346 during the 2018 season. His batting average was the highest of all players for that year. A player's batting average is computed by dividing the number of times a player has a hit by the player's total number of at-bats. BA= Number of Hits Number of At-Bats Notice that this formula looks a lot like a probability where the sample space is the set of all at-bats and the event is getting a hit. When fans talk about batting averages, they commonly think of it in terms of probability. That is, if a player is batting .250, then there is a 25% chance that they will get a hit at their next at-bat. 1. Do you agree with the interpretation of the batting average as a probability? Is it possible to compute the theoretical probability that a player will get a hit when at bat?…
