Basic probability of single events

What you'll learn

1. Define probability and calculate P(E) = favorable outcomes / total outcomes for simple events
2. Read probabilities directly from two-way frequency tables, bar charts, and circle graphs
3. Use the complement rule P(not A) = 1 - P(A) to find probabilities efficiently
4. Apply the addition rule P(A or B) = P(A) + P(B) - P(A and B) for compound events
