Finite and Infinite Sets

**Learning Outcome**: The learner demonstrates the knowledge of sets to solve problems in real life situations. **Content**: Finite and infinite sets; Subsets; Venn diagram (2 events); Probability **Subject Competences**: Identifies finite and infinite sets; Forms subsets from finite sets; Derives the formula for finding the number of subsets; Applies the formula to find number of subsets; Determines the number of subsets; Represents information on Venn diagrams; Solves problems involving Venn diagrams; Works out probability of events using Venn diagrams **Background**: "This is a continuation of work on sets studied in the previous classes. Teachers should not give the learners the formula for calculating the number of subsets in a set. Instead they should help the learners to derive the formula on their own. Finite and infinite sets are introduced and these concepts should be explained to the learner properly." **Guidance to the Teacher**: "Use application of work covered on sets in previous classes at the beginning of the topic."
