P(B | A) - ANSWER✅conditional probability
,P(A and B)=P(A) • P(B) - ANSWER✅multiplication rule- independent events
P(A and B)= P(A) • P(B|A) - ANSWER✅multiplication rule- dependent events
P(A or B)= P(A) + P(B) - ANSWER✅addition rule- Disjoint
P(A or B)= P(A) + P(B) - P(A and B) - ANSWER✅addition rule- non-Disjoint
