Question
If A denotes some event, what does Upper A over bar A denote? If P(A)equals=0.996, what is the value of P(Upper A overbarA)? If P(A)equals=0.996, is Upper A overbarA unlikely?
What does Upper A overbarA denote?
A. Event Upper A overbarA denotes the complement of event A, meaning that Upper A overbarA and A share some but not all outcomes.
B. Events A and Upper A overbarA share all outcomes.
C. Event Upper A overbarA is always unlikely.
D. Event Upper A overbarA denotes the complement of event A, meaning that Upper A overbarA consists of all outcomes in which event A does not occur.
If P(A)equals=0.996, what is the value of P(Upper A overbarA)?
P(Upper A overbarA)=?
(Type an integer or a decimal.)
If P(A)equals=0.996, is Upper A overbarA unlikely?
Yes or No?
Explanation / Answer
D. Event A-bar denotes the complement of event A, meaning that A-bar consists of all outcomes in which event A does not occur.
P(A-bar) = 1 - P(A) = 1 - 0.996 = 0.004
Yes, P(A-bar) is unlikely.
