\(\text{If} A \text{ and } B \text{ are independent events with }P(A)=0.8 \text{ and } P(B)=0.4,\text{ then the value of } P(A\cup B) \text{ is: \)
- A 0.58
- B 0.66
- C 0.88
- D 0.98
Answer & Solution
Correct Answer
(C) 0.88
Step-by-step Solution
Detailed explanation
\(P(A \cup B) = P(A) + P(B) - P(A)P(B)\) \(P(A \cup B) = 0.8 + 0.4 - (0.8)(0.4) = 1.2 - 0.32 = 0.88\)
