If A and B are independent events, P(A)=0.11 , and P(B)=0.74 , what is P(B|A) ?
For independent events
P(A and B) =P(A)*P(B)
using the formula P(B|A) = P(A and B)/P(A) = [P(A)*P(B)]/P(A) = P(B)..........P(A) cancelled out.
so, P(B|A) = P(B)
we have P(B) = 0.74
therefore, P(B|A) = 0.74
If A and B are independent events, P(A)=0.11 , and P(B)=0.74 , what is P(B|A) ?
1 point) lf P(A)-0.4, P(B)-0.4, and P(A U B) 0.74, then (a) Are events A and B independent? (enter YES or NO) NO (b) Are A and B mutually exclusive? (enter YES or NO) NO
Given P(A) = 0.21, P(B) = 0.11, and P(A or B) = 0.23, are events A and B mutually exclusive? Question 2 options: No, they are not mutually exclusive.
Two events A and B are independent, P(A) = .25 and P(B) = .30 .
What is the probability of P(A∩B)=
.055
.06
.30
.075
.25
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?
If events A and B are independent, then P(B|A) is equal to ________. A. P(A) B. P(B) C. P(A∩B) D. P(AUB)
#8. Let A and B be two independent events with P(A)-0.4 and P(A U B)-0.64. What is P(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).
6. Independent events A and B are such that P(A) = a, P(B) = 2a and P(A U B) = 5/8. Find P(A) and P(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).
If A and B are independent events with P(A) = .2 and P(B) = .6, then P(A ∪ B) = _____. a. .12 b. .68 c. .62 d. .60
