Probability Flashcards
1
Q
What does Pr(ō) mean and how is it found?
A
The compliment to Pr(O), found by subtracting the probability of O from 1
2
Q
What does Pr(F ∩ G) mean?
A
The intersection of F and G, found by multiplying the probability of F by G
3
Q
What does Pr(F ∪ G) mean?
A
The union of F and G, either F or G or both occur. Found Pr(F)+Pr(G)−Pr(F ∩G)
4
Q
What happens if F and G are independent and the intersection wants to be found?
A
The probability of F and G are multiplied
5
Q
How would you find the probability of F occurring given that G has occurred?
A
Pr(F|G) = Pr(F ∩ G)/Pr(G)
