(17) Which of the following statements is true? (1) The set of all possible events of an experiment is called the sample space, S. (2) If an experiment is performed more than once, one and only one event can occur. (3) If two events A and B are mutually exclusive, then P(AUB) = 0. (4) A simple event is the outcome observed on a single repetition of an experiment.
1. (10 pts) Consider two events, A and B, for which we have the following probabilities. P(A)=0.5 P(B) = 0.2 P(AB) 0.7 A. Find the probability P( AB) B. Find the probability P(AUB)
QUESTION If A and 8 are two mutually exclusive events and P(A) -0.5 and P(B) -0.3, then the probability of joint event AU 8 should be QUESTION 2 Does the following Venn Diagram correctly describe the event (AUB)nC O True False
Two events A and B are such that P(A) = 0.4, P(B) = 0.5, and P(AUB) = 0.7. (a) Find P(A n B). 0.2 (b) Find P(AUB). 0.8 (c) Find P(An B). 0.3 (d) Find P(AB). (Enter your probability as a fraction.) 1/2
Two events A and B are such that P(A)2, P(B).3, and P(AUB) -4. Find following: a P(An B) b P(AUB) d P(AB) If A and B are independent events with P(A)and P(B) .2, find the following: a P(AUB) b PAnB) c P(AU B)
Which of the following statements is true regarding economic events? a. The signing of a service contract is an example of an external event that is recorded in the accounting records. b. Every event which affects an entity can be identified from a source document. c. All internal and external events must be measured with sufficient reliability. d. External events involve exchanges between an entity and another entity outside the company.
1) True or False: For any two events, A and B, conditional probability is always less than unconditional probability, i.e. P[B|A] < P[B].
A and B are two statistically independent events, assume the probability of A is 0.4 and the probability of B is 0.5. 1) Determine the P(An B). [The answer should be a number rounded to five decimal places, don't use symbols such as %] 2) Determine the P(AUB). [The answer should be a number rounded to five decimal places, don't use symbols such as %]
2. a) Let A and B be two events such that P(A) 4, P(B) .5 and P(AnB) 3 Find P(AUB). b) Let A and B be two events such that P(A)-5, P(B) 3 and P(AUB) .6. Find P(An B)
consider Question 8 (0.1 points) Consider any two events A and B, such that P(A) = 0 and PB) +0. Which of the following statements is always FALSE? a) If events A and B are independent, then P(AB) = PA) and P BIA) - PB). b) If events A and B are disjoint, then PA and B) - 0. c) If events A and B are independent, then P{A and B) - 0. d) If events A and B are...
