Answer:
A and B are not independent events because P(A|B)≠P(A)
is the correct answer.
Step-by-step explanation:
If A and B are independent then we must have
P(AB) = P(A) P(B) and also
P(A/B) = P(A)
We are given that
A and B are two events.
Let P(A)=0.5 , P(B)=0.25 , and P(A and B)=0.15 .
P(A/B) = P(AB)/P(B) = 0.15/0.5 = 0.3
i.e. P(A/B) is not equal P(A)
Similarly P(B/A) = P(AB)/P(A) = 0.15/0.25 = 0.6 not equal to P(B)
Hence A and B are not independent.
Answer:
28
Step-by-step explanation:
6 X 10= 60, 60 X 2= 120, 6 X 5 = 30 120 + 30 = 150, 6X 3 = 18 150 + 18 = 168, 10+ 10 + 5 +3 = 28
Answer: B 53/20
Step-by-step explanation:
.9+1.75 =2.65
2.65 = 53/20
Steve's monthly income will be $418.75 per month at this salary level, because $5025 / 12 months equals $418.75 per month.
