Document Summary

A set is a well- defined collection of objects, elements or members of sets. A = {1,2,3,4} (this is an example of objects) B= {x, y, z} this is an example of members or objects. Write the following sets in two ways list and describe. Reminder: when you calculate for your vim diagram for your project make assumptions. How many stocks had none of the characteristics set cp or d: their price to earnings ratio was less than 20 (set p, their dividend per share was at least . 50 (set d). Define: p = { x: x is } , c = { } and d = { } Yes it is possible for sets to contain no numbers they are called empty sets, or null sets and it is indicated by or by [] We are adding everything from one set to the other set. P = {x: x is a stock with price-to-earnings ratio < 20} 16.
