WebGiven P(A) = 0.4, P(B) = 0.5 and P(A⋃B)=0.9,then: (a) A and B are not mutually exclusive events (b) A and B are equally likely events (c) A and Bare independent events (d) A and B are mutually exclusive events MCQ 6.57 If P(B/A) = 0.50 and P(A⋂B) = 0.40, then p(A) will be equal to: (a) 0.40 (b) 0.50 (c) 0.80 (d) 1 MCQ 6.58 WebThe probability of the entire outcome space is 100%. (P(S) = 100%. because the outcome space contains every possible outcome.) If two events are disjoint, the probability that either of the events happens is the sum of the probabilities that each happens. (If AB = {}, P(A ∪ B) = P(A) + P(B).)

Web17 jul. 2024 · P (A B) = P ( A⋂B ) / P (B) Bayes’s Theorem It is the formula that shows the relation between probabilities of occurrences of mutually dependent events i.e. it given the relation between their conditional probabilities. Given an event A and another event B, according to bayes’ theorem, P (A/B) = {P (B/A) * P (A)} / P (B) Web#9 If A is a subset of B then P (A) is less than or equal to P (B)- monotonicity property- proof Phil Chan 35.2K subscribers Subscribe 20K views 10 years ago BUT, the reverse is not... grad school ubc
3.3: Conditional Probability and Independent Events
WebIf A⊂B, then A∩B is A B B A∖B C A D B∖A Easy Solution Verified by Toppr Correct option is C) We are given that A is the subset of B ⇒ Every element of A is an element of B. Therefore, the intersection elements of sets A and B are A∩B=A. Was this answer helpful? 0 0 Similar questions Web20K views 10 years ago. BUT, the reverse is not true ie.If P (A) is less than or equal to P (B), it doesnt follow that A must be a subset of B. Proofs given for both claims.
