Nov. 14, 2023: Unit 6 notes (probability) - Coggle Diagram

- - - - ?/36
        
        the denominator is 36 because each dice has 6 sides: so 6x6 = 36
        
        you can also find the denominator by laying out all the possible outcomes of rolling the dice (including all possibilities that the dice will not add up to 7)
      - 6/36
        
        there are 6 possible outcomes of getting to the "required"/"expected sum
  - - - 2 numbers "competing"
        
        A outcomes to non-A outcomes
    - - possible number of outcomes of rolling a sum of 10: 3
        
        do not count getting 5 and 5 twice... that is a permutation
      - non-A outcomes: 36-3 = 33
        
        6x6=36 possible outcomes/combinations of rolling two dice
      - ratio is 1:11
      - formula = A outcomes : non-A outcomes
  - - - the chance that A happens, assuming that B happens too
    - - P(SD|Surf)
        
        (probability of Shark Death, assuming that the person is surfing)
        
        a surfing person can look like a seal (prey) to sharks
        
        P(SD) = 6/8 000 000 000
        
        P(SD|Surf) > 6/8 000 000 000
        
        when "B" happens (surfing, in this case) changes (raises, in this case) the chances of A happening (dying because of a shark)
    - - P(GMV|DT) = 0.73 OR P(DT|GMV) = 0.73
        
        which one would be the discouraging formula?
        
        P(DT|GMV)
- - - - P(H)
      - P(T)
      - P(H + T)
        
        an addition of the two possibilities when it is OR
    - - Even numbers: 2, 4, 6
      - P(Ev) = 3/6
      - Prime numbers:
      - P(Pr) = 4/6
        
        4 prime numbers on a dice
