Lesson review:
Today we have finished the second half of Chapter 8: Basic Probability Techniques and Chapter 9: Think about it!
- Addition or Multiplication
We add probabilities of exclusive events: P(A or B) = P(A) + P(B);
and multiply probabilities of independent events: P(A and B) = P(A) X P(B) - Independent VS Dependent Events
Independent Events: the probability that one event occurs in no way affects the probability of the other event occurring.
Dependent Events: the probability of one event occurring influences the likelihood of the other event. - Avoid unnecessary computation:
1) take advantage of symmetry
2) ignore the irrelevant information
3) consider multiple events at once instead of dealing with them separately
4) be flexible, think out of the box!
