If, P(A∪B)=0.7, P(A)=0.2, and P(A∩B)=0.15
find P(B). Assume that A and B are events.
if, P(A∪B)=0.7, P(A)=0.2, and P(A∩B)=0.15
find P(B). Assume that A and B are events.
Answer : we knot that ,
P(A∪B) = P(A) + P(B) - P(A∩B)
therefore
P(B) = P(A∪B) - P(A) + P(A∩B)
P(B) = 0.7 - 0.2 + 0.15
P(B) = 0.65
If, P(A∪B)=0.7, P(A)=0.2, and P(A∩B)=0.15 find P(B). Assume that A and B are events.
let A and B be any 2 events with p(A)=0.2; P(AUB)=0.35; P(A and B)= 0.15 find P(A|B) QUESTION 25 Let A and B be any 2 events with p(A) 0.2; P(AUB) 0.35; P(A and B) 0.15 a.0.25 Find P(A|B) b.0.5 c.0.6 d.0.4

If P(B)=0.2,P(A | B)=0.7,P(B)=0.8, and P(A|B)=0.5, find P(B | A).
1. (15pts) Events A, B and C are such that P(A) = 0.7, P(B) = 0.6, P(C) = 0.5, P(AnB) = 0.4 , P(AnC) = 0.3, P(BnC) = 0.2, P(AnBnC) Find (a) either B or C happens (b) at least one of A, B, C happens; c) exactly one of A, B, or C happens. 0.1.
Suppose that A and B are mutually exclusive and complementary events, such that P(A)=0.7 and P(B)=0.3. Consider another event C such that P(C/A)-0.2 and P(C/B)=0.3. What is P(C)?
