24) We proceed with a proof by contradiction.
- We assume that it is not the case that "at least 10 days of any 64 days chosen fall on the same
day of the week."
- This means that "less than 10 days of any 64 days chosen fall on the same day of the week."

8) For each of the sets in Exercise 7, determine whether cfw_2 (A set cfw_2) is an element of that set.
a) cfw_x Rx is aninteger greater than1
To explain this set, we have the following elements cfw_2, 3, 4,5, 6, 7,8 , . In this set we have an element 2
Sets
A set is an unordered collection of objects Examples: cfw_apple,orange,pear is a set. cfw_1,2,3,4,5 is a set.
The objects of a set are called the elements (or members) of a set. The set is said to contain its elements.

Review
Recall: Proof methods for a statement p q Direct: Assume p is true, prove q is true. By Contraposition: Assume q is true, prove that p is true. By Contradiction: Assume p is true, assume q is true. If a contradiction is found, the proof is comple
Example
Show that ( p ( p q) and p q are logically equivalent by developing a series of logical equivalences.

Induction: Review
When using Mathematical Induction to prove that a property P(n) holds for all positive integers n, we must do the following two steps: 1)Basis step: Show that P(1) is true. 2)Demonstrate that if P(k) is true for arbitrary k, then P(k+1
