**Show that if events A B C are independent then the**

A and B are independent random variables. (A) I only (B) II only (C) I and II (D) Neither statement is true. (E) It is not possible to answer this question, based on the information given.... Suppose for events A, B, and C connected to some random experiment, A, B, and C are independent and P (A) = 0.95, P (B) = 0.73, and P (C) = 0.62. Compute the indicated probability, or explain why there is not enough information to do so.

**Exam 1 Practice Questions Long List**

elements of B that are not in A (A c B) elements of both A and B (AB) If A and B are independent, so are A and B c; A c and B c; A c and B. What kinds of events are independent? The outcomes of successive tosses of a fair coin, the outcomes of random draws from a box with replacement, etc. Draws without replacement are dependent, because what can happen on a given draw depends on what... Corollary If A and B are independent, so are A0 and B0. Apply the Proposition twice, ﬁrst to A and B (to show that A and B 0 are indepen- dent), and then to B 0 and A (to show that B 0 and A 0 are independent).

**Proof Assignment #3 Dartmouth College**

If A is independent of B and A is independent of C then is B not independent of C? No. A can be independent of both B and C and this doesn't give use any information about the relationship between B and C.... Suppose for events A, B, and C connected to some random experiment, A, B, and C are independent and P (A) = 0.95, P (B) = 0.73, and P (C) = 0.62. Compute the indicated probability, or explain why there is not enough information to do so.

**If A and B are independent events then are A and B**

elements of B that are not in A (A c B) elements of both A and B (AB) If A and B are independent, so are A and B c; A c and B c; A c and B. What kinds of events are independent? The outcomes of successive tosses of a fair coin, the outcomes of random draws from a box with replacement, etc. Draws without replacement are dependent, because what can happen on a given draw depends on what... 21/02/2008 · Best Answer: I will use A' for notA. First you need to show that A', B and C' are pairwise independent. For example show that A' and B are independent ie, that

## How To Show A B And C Are Not Indepedent

### SOLUTION Let events A, B, and C be winning the first, second, and third games. The three events are independent and have experimental probabilities based on the regular season games.

- If the events A abd B are exclusive, then P(A ¢ B) = 0, and we get the familiar formula P(A [ B) = P ( A )+ P ( B ) : The inclusion-exclusion rule can be generalized to unions of arbitrary number of events.
- knowing whether A occured does not change the probability of B. Mathematically, can say in two equivalent ways: P(B|A)=P(B) P(A and B)=P(B ∩ A)=P(B) × P(A). Important to distinguish independence from mutually exclusive which would say B ∩ A is empty (cannot happen). Example. Deal 2 cards from deck AﬁrstcardisAce C second card is Ace P(C|A)= 3 51 P(C)= 4 52 (last class). So A and C are
- elements of B that are not in A (A c B) elements of both A and B (AB) If A and B are independent, so are A and B c; A c and B c; A c and B. What kinds of events are independent? The outcomes of successive tosses of a fair coin, the outcomes of random draws from a box with replacement, etc. Draws without replacement are dependent, because what can happen on a given draw depends on what
- Give an example of 3 events A,B,C which are pairwise independent but not independent. Hint: find an example where whether C occurs is completely determined if we know whether A occurred and whether B occurred, but com- pletely undetermined if we know only one of these things.
