Forty five percent of the sales are chocolate, while 30% are strawberry, with the rest vanilla flavored. Sales are by the cone or the cup. The percentages of cones sales for chocolate, strawberry, and vanilla, are 75%, 60%, and 40%, respectively. For a randomly selected sale, define the following events: = chocolate chosen = strawberry chosen = vanilla chosen = ice cream on a cone ice cream in a cup Find the probability that the ice cream was chocolate flavor, given that it was sold in a cup. Place your answer, rounded to 4 decimal places, in the blank. For exampe, 0.3456 would be a legitimate entry. 29.4 Answer Key: 0.2941 Question 17 of 25 1.0/ 1.0 Points Accepted characters: The Big Triple at the local racetrack consists of picking the correct order of finish of the first three horses in the ninth race.

Skittles are a hard shelled, fruit flavored candy loved by many today. Skittles first came into existence in Britain in 1974. They were introduced to the United States in 1979 but weren’t actually produced until 1982 where they are now a product of Wrigley. The Skittles catchphrase, “Taste the Rainbow” was came about in 1994. The Skittles Company has a variety of flavors from Sour Skittles, released in 2000; Bubble Gum Skittles, released in 2004; and Smoothie Fruit Mix, released in 2005. The Original Skittles consist of a strawberry flavor, an orange flavor, a lemon flavor, a green apple flavor, and a grape flavor. According to Wrigley, Skittles colors/flavors are all evenly distributed in each of their packs. So our question in hand was, is this claim actually true and if so, is the ratio of flavors in the regular sized (2.17 oz.) Skittles packs the same as the Fun Sized packs of Skittles? We chose do experiment with this because collectively as a group, we all love Skittles and from our understanding we initially assumed prior to conducting the experiment that Skittles had an equal number of flavors in each pack. There are five flavors in a pack, so that means that each pack should have 20% of each flavor. We decided that our null hypothesis would be H0:
In Nella Larsen’s Passing, Irene Redfield and Clare Kendry show us a great deal about race and sexuality in the 1920s. Both are extremely light-skinned women of African-American descent. However similar they appear to be, their views on race, a very controversial issue at the time, differ significantly. Clare chooses to use her physical appearance as an advantage in America’s racist and sexist society, leaving behind everything that connects her to her African-American identity. She presents herself as an object of sexual desire, flaunting herself to gain attention. Irene is practically the opposite, deciding that she wants to remain with the label of being black. She is subtle with her

In order to obtain a random sample, three bags of M&Ms were purchased from different locations. Each bag of M&Ms was a 1.69oz bag that was the standard plain version of the candy. The M&Ms were then sorted by color and this data was collected and compiled. These results were also added to a larger sample
The following statistics stated in the case indicate that “23% of respondents would definitely buy the Montreaux dark chocolate with fruit product and 40% would probably buy the product.” These average ratings strongly suggest that this product should be introduced into the market very gradually. This strategy would enable the company to evaluate consumer buying patterns so that the company could determine future production levels and future marketing strategies that benefit both the company and the consumer. Financial information given in the case also indicates that the company needs to introduce this product very conservatively. Exhibit 1 informs that with 5.98 million total purchases, low awareness, low ACV and mediocre product, Montreaux would gross $17.44 million. Exhibit 2 shows that with medium awareness, medium ACV and an average product Montreaux would gross $25.1 million. These figures do not meet Montreaux’s objective of earning at least $30 million in its first year. Exhibit 3 shows a slightly improved situation: with high awareness, high ACV, and an excellent product, Montreaux would gross
