Answer 1

Answer:

Formula for the probability of A and B (independent events): p(A and B) = p(A) * p(B). If the probability of one event doesn't affect the other, you have an independent event. All you do is multiply the probability of one by the probability of another.

Answer 2

Answer:

the extent to which an event is likely to occur, measured by the ratio of the favourable cases to the whole number of cases possible.

Basic Probability Formulas:-

• Probability Range. 0 ≤ P(A) ≤ 1.
• Rule of Complementary Events. P(AC) + P(A) = 1.
• Rule of Addition. P(A∪B) = P(A) + P(B) - P(A∩B)
• Disjoint Events. Events A and B are disjoint iff. ...
• Conditional Probability. P(A | B) = P(A∩B) / P(B)
• Bayes Formula. P(A | B) = P(B | A) ⋅ P(A) / P(B)
• Independent Events. ...
• Cumulative Distribution Function
