1. Consider two independent events, A and B, where 0< P(A) <1,0< P(B)< 1. Prove that A and B' are independent as well.
7. If A and B are independent events, then P(A and B) equals a. b. c. P(A) + P(B/A). P(A) x P(B). P(A) +P(B). d. P(A/B) +P(B/A) 8.Which formula represents the probability of the complement of event A? b. 1-P(A) c. P(A d. P(A)-1 9. The simultaneous occurrence of two events is called a. prior probability b. subjective probability c. conditional probability d. joint probability 10. If the probability of an event is 0.3, that means the event has a...
Classify the events as dependent or independent: Events A and B where P(A) = 0.5, P(B) = 0.2, and P(A and B) = 0.09 Independent or Dependent? 0.5 x 0.2=0.10 which does not equal 0.09, does this mean that the correct answer is dependent?
1. (a) Two events A and B are such that P(A)=1/4,P(A/B)=1/2,and P(B/A)=2/3.Are A and B independent events? Are A and B mutually exclusive events? (b) How many sample of size 4 can be drawn without replacement from the population 0,3,6,3,18?compute the sampling distribution of the mean, then identify the relationship between the population and sampling distribution standard deviations?
Consider two independent events, A and B, where 0くP(A) < 1,0くP(8)く1. Prove that A' and B' are independent as well.
Let A and B be two independent events. If P(A) = .25, what can you say about P(A | B)? Cannot find it since P(A and B) is not known. Cannot find it since P(B) is not known. Cannot find it since both P(A and B) and P( B) are not known. It is equal to .5. It is equal to .25.
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)
Suppose two events A and B are two independent events with P(A) > P(B) and P(A U B) = 0.626 and PA กั B) 0.144, determine the values of P(A) and P(B).
There are two events, A and B, where we know that P(A) > 0 and P(B) > 0. If we know these events are mutually exclusive (disjoint), then we can conclude that these events are: A. independant b. dependant c. both independant and dependant d. neither (we cannot know without the values)
Help please!
Suppose two events A and B are two independent events with P(A) > P(B) and P(AU B) = 0.626 and PAn B)-0.144, determine the values of P(A) and P(B). 9.
