Chapter 4:4.1-4 A wheel offortune has the integers from 1 to 25 randomly placed on it. Show that regardless of how the numbers arepositioned on the wheel, there are three adjacent numbers whose sum is atleast 39. 4.3-4 If a, b, c ∈ Z+ and a|bc, does it follow that a|b or a|c? Chapter5:5.1-8 Logic chipsare taken from a container, tested individually, and labeled defective orgood. The testing process is continueduntil either two defective chips are found or five chips are tested in total. Using a treediagram, exhibit a sample space for this process. 5.7-6(See the definition 5.23 on page 290for help with this problem.) Let f,g: Z+→R be defined as follows: Verify thatf ∉ O(g) and g∉O(f)
