Answer:

0.94

Step-by-step explanation:

Formula; P(AUB) = P(A) + P(B) - P(AB).

P(A) = 0.7

P(B) = 0.8

P(AB) = 0.56

=  0.7 + 0.8 - 0.56

=  0.94

Hence, P(A U B) = 0.94

Answer:

P(A ∪ B) = 0.94

Step-by-step explanation:

P(A) = 0.7

P(B) = 0.8

P (A ∩ B) = 0.56

P(A ∪ B) = P(A) + P(B) - (A ∩ B)

⇒ P(A ∪ B) = 0.7 + 0.8 - 0.56

⇒ P(A ∪ B) = 0.94
