If A and B are independent events, show that A' and B are also independent. [Hint: First establish a relationship between P(A'n B), P(B), and P(A n B).]P(B) = P(A'n B) + ---Select------Select-- O = P(B) P(An B)Since A and B are independent, we have the following.P(A'n B)= P(B)---Select--P(A' n B) = [1 P(A)] ---Select--- )P(A'n B)= ---Select--->Thus, A' and B are independent.

We have given that events A and B are independent.As A and B are independent we have the following…

Look at the 4 probability rules beow , an provide a REAL LIFE example for each. Also, with a Real LIfe EXAMPLE, explain how Disjoint events CAN be dependent. Rule 1. The probability P(A) of any event A satisfies 0 ≤ P(A) ≤ 1. Rule 2. If S is the sample space in a probability model, then P(S) = 1. Rule 3. Two events A and B are disjoint if they have no outcomes in common and so can never occur together. If A and B are disjoint, P(A or B) = P(A) + P(B) This is the addition rule for disjoint events. Rule 4. For any event A, P(A does not occur) = 1 − P(A)
(a) For each one of the statements below say whether the statement is true or false, explaining your answer. i. Let A and B be two events such that P(A) > 0 and P(B) > 0. If it holds that P(A|B) = 0, then P(B|A) = 1. 4 i. For two independent events A and B such that P(A) > 0) and P(B) > 0, then: P(AUB) = P(A) = P(B). iii. For a random variable X, then: Var(X)> Var(X + 2). iv. A random sample of size n is a sequence of n independent and non-identically distributed random variables. v. The standard normal distribution has fatter tails than the Student's t distribution with finite degrees of freedom. istribution with
A restaurant owner wanted to know which time range are popular among the customers. Data were collected on the following events: L = a customer usually visits the restaurant during lunch time D = a customer usually visits the restaurant during dinner time Data collected suggest the following: P( L ) = 0.6 P( D ) = 0.7 P( L and D) = 0.3 What is the possibility that a customer only visit the restaurant during dinner time
D) Are the events male cheated and female right independent? Show the computations needed to justify your answer.
There are 13 questions in this set. As you go through these questions, use relevant information from previous questions. A manufactured good has two inputs, X is the price of input #1. Y is the price of input #2. These prices are in dollars. Below is the bivariate probability distribution of the prices of these inputs. The covariance between X and Y is 0.4. You will need the covariance later in this set so remember to come back to this value and use it! What is the probability that the price of input #1 will be its smallest value (10)?
