I could have called it aīunch of different things. The number 3, the number 12, the number 5, and the number 13. So let's say I haveĪ set X, and it has the distinct objects in it, But the numbers will beĮasy to deal with just because- well, they're numbers. So for example, I could haveĪ set- let's call this set X. So a set is really just aĬollection of distinct objects. Of a set and also perform some operations on sets. Video is familiarize ourselves with the notion if it is done right you don't realize it's there and you might start to think you don't need it. Math education is kind of like tech support. there will just be problems that you can now solve without realizing you wouldn't have been able to solve them before. you would either just bypass the problem or possibly not even recognize the situation as a problem in the first place.Īnd if you do learn set theory you most likely won't recognize that you are even using it. you won't slap yourself on the forehead and say "if I only knew set theory!". If you don't have a particular technique in math you will just ignore problems that could have been solved using that technique. and if you don't even know it can be fixed you just write it off. If you know it can be fixed but you don't have the tools then you are frustrated.

If you have something you want to fix and you know how to fix it and you have the proper tools then the thing gets fixed.
I tell my students to think of math as a toolbox. Each technique you learn is a tool that might become useful.
Mathematics is a set of tools and techniques that helps us model the truth of the real world in different, sometimes more useful ways. You look at a situation and create a picture of that situation in your head. a Complete the Venn Diagram using the information given above.The truth of a problem exists only in the real world, however you see a problem is a representation of that problem in your mind. At a birthday party, 11 guests wanted cake and ice cream, 9 asked for only a piece of cake, 5 just wanted ice cream, and 2 of the guests did not want anything at all. Use the data in the table to determine the if it is more likely that someone drinks coffee given that they stay up late or more likely that someone stays up late given that they drink coffee. If one student is randomly chosen from the group, what is the probability that they are taking tech given that they are taking art? Express your answer to the nearest tenth of a percent. In a group of 190 students, 112 students are taking a tech course, 74 are taking an art class, and 62 are taking both courses. If 63% of the employees work nights, what percent, to the nearest tenth, of the employees who work nights are working weekends? 3. At a local restaurant, 52% of the employees work both nights and weekends. If there is a 0.85 probability that he goes running and a 0.65 probability that he has homework, determine the probability that Jeremiah goes running given that he has homework. On any given day, the probability that Jeremiah goes for a run and has homework to complete is 0.55. Name:_ Unit #12 - Conditional Probability - Additional Practice Common Core Algebra II 1.
