P(A ∩ B)=0
since they're indepedent they dont have any common elements
P (A ∪ B) =P(A) + P(B)  P(A ∩ B) =P(A) + P(B)=0.1 +0.4=0.5

What does P(ā) mean? Is that the complement of A or in other words:
P(ā) = 1  P(A) = 0.10 => P(A) = 0.9 and P(B) = 0.4
P(A ∩ B) = Probability of A and B both occurring = (0.9)(0.4) = 0.36
P(A ∪ B) = Probability of either A or B occurring but not both = (0.9)(0.6) + 0.4(0.1) = 0.58
