Suppose the events A and B are disjoint with P(A) = 0.5 and P(B) = 0.25. Find the probability of A or B occurring, P(A or B).
(7) The events A and B are mutually exclusive (disjoint). If P(A) = 0.7 and P(B) = 0.2, what is P(A or B)? A) 0.14 B) 0 C) 0.9 D) 0.5 (8) The events A and B are mutually exclusive (disjoint). If P(A) = 0.2 and P(B) = 0.1, what is P(A and B)? A) 0.02 B) 0 C) 0.5 D) 0.3 (9) A probability experiment is conducted in which the sample space of the experiment is S = {1,...
(1) Suppose that A and B are events with P[A] = 0.4 and P[B] = 0.7. Show that 0.1 < PAB < 0.4. Justify your answer clearly. P(ANB) - PCA) PCB) = 0.4.0.7 = 0.28 with 0.15 0.28 <0.4 PLA) occuring 04 P(B) occuring 0.7 P of both events occuring at the same time should be = 0.28 which is in Ran 0,4 1028 0.7 2/10
Let A and B be two disjoint events such that P(A) = 0.29 and P(B) = 0.36. What is P(A and B)?
Let A and B be two disjoint events such that P(A) = 0.25 and P(B) = 0.45. What is P(A or B)?
If A and B are independent events such that P(A) = 0.43 and P(B) = 0.56, then find the value of P(A | B) then find P (A and B).
Suppose that A and B are independent events such that P (A) = 0.40 and P(B) = 0.60. Find P(An B) and P(AUB). (If necessary, consult a list of formulas.) (2) P(AnB) = 1 (b) P(AUB) Х 5 ?
2) Suppose A and B are independent events, then() is incorrect. PCAIB) P(A) O P(AnB) P(A)P(B) P(AUB)-P(A)+P(B) 0:(AIB) = P(A)
2. Suppose A and B are two events. Use the axioms of probability to prove the following (a) P(AnB) 2 P(A) P(B) 1 (b) Show that the probability that one and only one of the events A or B occurs is P(A)+ P(B) -2P(AnB). 3. There are 9 lights labeled 1 to 9, and they are lined up in a row in Boelter Hall. or budget reasons, we are going to turn off 3 of them. For security purposes, we...
5. Suppose E, F, and G are three disjoint events where P(E)- .15, P(F)- .25, and P(G).60. Find the following: (a) P(F or G) (b) P(Ec) (c) P((E or F)c) (d) P(FnG) 6. A new diagnostic test for a disease is studied. It is known whether or not these 100 individuals have the disease and the diagnostic test is administered. The results are as follows infectedhealthy tested positive tested negative 40 10 45 Let E-randomly selected person is infected and...
