- Show All Work Please... Consider a deck of cards that has 80 cards. Of these, 60 have a color and 20 are “wild.” The 60 cards with a color are either red, yellow, green, or blue, with 15 of each color. Two cards are said to “match” if any of the following are true: they have the same color, one is a color and the other is wild, or both are wild. (This is a simplified version of the card game UNO.) Two cards are drawn from the well-shuffled deck without replacement. Express your answers to (a)-(d) as simplified fractions or as percentages rounded to the nearest hundredth of a percent. (a) What is the chance that both are blue? _________ (b) What is the chance that both are color cards and they are the same color? _________ (c) What is the chance that one is a color card and the other is wild? _________ (d) What is the chance that they match, using the definition above? _________ (e) Are the following two events mutually…A panel of Judges A and B graded seven debators and independently awarded the following marks : Debator 1 3 4.

For 4,901 out of the 4902 persons who were HIV negative, he company's test correctly predicted such a negative result, but incorrectly predicted a positive result for the one remaining person.
