Answer:
The value of P(A ∪ B) is 0.682 to the nearest thousandth
Step-by-step explanation:
The addition rule of probability is:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B), where P(A ∪ B) is probability A or B , P(A ∩ B) is probability A and B
∵ P(A) = 0.33
∵ P(B) = 0.6
∵ P(A ∩ B) = 0.248
- Substitute these values in the rule above
∴ P(A ∪ B) = 0.33 + 0.6 - 0.248
∴ P(A ∪ B) = 0.682
The value of P(A ∪ B) is 0.682 to the nearest thousandth
