(a) Are following claims correct? Why / Why not? (i) If two events A and B...
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?
Problem 3: Conditional Probabilities Let A and B be events. Show that P(An B | B) = P(A | B), assuming P(B) > 0.
1. Fundamentals: (a) Briefly, state why probability is important for statisticians (b) Let random variables X, Y, and Z be distributed according to the following table. probability 1/4 1/4 i. True or false: X and Y are independent. Explain. ii. True or false: X and Y are conditionally independent given Z. Explain. (c) Let A, B, and D be events, where 0< PD) 1. i. Prove that P(An B P(AB) 2 P(A) +P(B) 1. ii. Suppose that P(AD) 2 P(B|D)...
T-1 Suppose two events A and B are mutually exclusive and PAI 0, P[B] 0 . Consider the following statements: i) P(An B)=0 ii) P(A U B) = P(A) + P(B) iii) A and B are statistically independent. Choose the correct statement. A) Only i) is true. B) Only ii) is true. C) Only iii is true. D) Only i) and i) are true. E) i), ii) and iii) are all true.
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.
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.
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.
#5 (4 pts.) Consider the following sample space S and events A and B. s-(-4 < x < 2, 6 < x < 12), A={-4 < x < 0}, B=(-1 x<2), A and B are: a. (mutually exclusive, independent) b. (mutually exclusive, dependent) c. (non-mutually exclusive, independent) d. (non-mutually exclusive, dependent) #6 (4 pts.) In problem #5 P(B-A)- c. 1/4 d. 1/6
IMPORTANT: I know the answer to the question is given below. However, I don't understand it. Please explain why A & B are independent when P(B)=1 and P(A)=0? Also, why are they not independent in all other cases? State whether the following is True (T) or not always True (F) If A C B then A and B are not independent 6 ane net independant. (F) for ACB, e events A TP ACB hen Ae know As Cwe indenpent whan...
