Answer: i think its 0.7 because its A and B together so
A = 0.4    B = 0.3
0.4+0.3 = 0.7

Answer:

B

Step-by-step explanation:

Probability Equation :

P (A ∪ B) = P (A) + P (B) - P (A ∩ B)

=============================================================

Given :

⇒ P (A) = 0.4

⇒ P (B) = 0.3

⇒ P (A ∩ B) = 0.1 (From diagram)

==========================================================

Solving :

⇒ P (A ∪ B) = 0.4 + 0.3 - 0.1

⇒ P (A ∪ B) = 0.6
