Step-by-step explanation: Since we have given, P(A) = 0.75 and P(A|B) =0.8 .
So, P(A∩B) = P(B|A)× P(A) = 0.8×0.75 =0.6 .
We have given P(B|A') = 0.6
P(A’∩B) = P(B|A')×P(A') = 0.6 × 0.25 = 0.15.
P(B) = P(A∩B) + P(A'∩B) = 0.6 + 0.15 = 0.75.
=> P(A|B) = (∩)()=0.60.75

Answer:
1.15x + 0.35x = 22.50
Step-by-step explanation:
Let x = number of days
If:
- DVD incurs an overdue fine of $1.15 per day
- book occurs an overdue fine of $0.35 per day
- total fine = $22.50
1.15x + 0.35x = 22.50
