Document Summary

Deductive/inductive reasoning: inductive reasoning: formulating possible rules based on a few examples or experiences, deductive reasoning: drawing conclusions using laws of logic. Venn diagrams: principle of inclusion-exclusion: a+b=(a union b)+(a intersectionb) When solving a venn diagram with three circles, start from the inside and work out label the part which all three categories apply x and create equations for each section denoting the amount of things that belongs in each. B=[1, 3, 5, 7, 9: a is not a subset of b because there is no element 2 in b. Matching elements with the elements in another set is much more basic than the idea of counting. A=5, how many subsets are there: 2^5=32 subsets 2x2x2x2x2. What is the cardinality of set a: a=4 since 16=2^4. The power of set a = p(a) the set of all of the subsets of a: a={a, b}
