"> Other Bookmarks Q1 (8 points) Consider the following partial combinatorial argument that n2 = n + 2 (n - i). 1= 1 Kamar and Serena are buying paint from a hardware store with n different colours in stock, labelled with integers from 1 to n. We count the number of ways they can each order a can of paint in two different ways. Method 1: Kamar chooses a colour for his paint (n choices) and Serena chooses a colour for her paint (n choices). By the Rule of Product, there are n2 different ways they can order paint. Method 2: First, there are n ways for Kamar and Serena to choose the same colour of paint. If they pick different colours, Finish the combinatorial argument by completing Method 2. + Drag and drop an image or PDF file or click to browse... MacBook Pro + S O &
