Problem 3You're a structural engineer working for a large construction firm. You purchase structuralbeams from three different suppliers: 20% from supplier A1, 20% from supplier A2, and 60%from supplier A3. Based on historical evidence, 10% of the beams from A1 are not directlyusable in commercial construction, same with 12% of beams from A2 and 4% from A3. What isthe probability that a particular beam will not be directly usable in commercial construction?

Three suppliers of structural beams : P(A1) = 20% = 0.20 P(A2) = 20% = 0.20 P(A3) = 60% = 0.60 Beams…
