Find the requested probability.
P(Ā) if P(A) = 0.8
P(Ā) =
P(Ā) = 1- P(A)
P(Ā) = 1- 0.8
P(Ā) = 0.2
P(Ā) = 1 - P(A) = 1 - 0.8 = 0.2
So, the probability of the complement of event A (denoted by Ā) is 0.2. Ā is the event that A does not occur.
1 - P(A)
P(Ā) = 1 - 0.8
P(Ā) = 0.2
To find the probability of the complement of event A, denoted as Ā, you can use the formula:
P(Ā) = 1 - P(A)
Given that P(A) = 0.8, you can substitute this value into the formula:
P(Ā) = 1 - 0.8
Simplifying the expression:
P(Ā) = 0.2
Therefore, the probability of the complement of event A, P(Ā), is 0.2.
