pick a new MATH 1700 text. She has 4 textbook options. The probability of a Pearson textbook being effective and cost-efficient is o.2. What is the probability I find at least one of the textbooks suitable (effective and cost-efficient) to consider for the next stage of evaluations? Problem 8. Suppose I want to select a dog breed at the Westminster dog show for the "Best in Show" award. I can also award and and 3rd place. There are 7 groups, each of which has a champion for the group. The Best in Show (as well as second and third place) are selected from these 7 champions. How many 1st, 2nd, and 3rd place orderings can happen? Problem 9. Suppose you're going to have a movie marathon over Thanksgiving break and pick 5 movies to watch. Your collection contains 8 movies. If order doesn't matter, how many different subsets of 5 movies are possible? Problem 10. Suppose a casino is designing a new game. It finds the amount of money customers are most likely to spend to play a game repeatedly is $1, so that's what it will charge. To keep them interested, suppose they want to make the payout upon a customer "win" $5 (meaning the casino loses $5 when they have to pay out and gains $1 when the customer loses). What should be the largest probability of a customer winning to ensure that the casino expects to make money on this game? /2 2 Activity Details NOV 14 000 F3 F4 F5 F9 F7 F8

Counting Principles

In statistics, the counting principle can be said to be the concept in which the quantity of an item is determined. There can be a single item, or a group of items, or items that are related to each other. In every possible set of items, the quantity of the possible item groups or their sorting measures can be determined with counting principles.
