Step 1

The set {x âˆˆ â„ and x < 3} can be described in two ways: a. Using descriptive form: The set consists of all real numbers x such that x is less than 3. b. Using roster form: The set can be written as {x | x is a real number and x is less than 3}. Show more…

Describe the set {x âˆˆ â„ and x < 3} a. Using descriptive form: The set consists of all real numbers x such that x is less than 3. b. Using roster form: The set can be written as {x | x is a real number and x is less than 3}. 4. Find the cardinality of the following sets: a. n{a, b, c}: The cardinality of this set is 3. b. n{3, 4, 3, 4}: The cardinality of this set is 2. c. n{January, June, July}: The cardinality of this set is 3. 5. Circle the best choice for each of the following sets: a. {c, d, e} and {5, 10, 15}: Neither b. {x, y} and {1, 2, 3}: Neither c. {x, y} and {y, x}: Equivalent
