### HideShow timer Statistics

Inspection system X and inspection system Y, though based on
different principles, each detect all product flaws but they each
also erroneously reject three percent of flawless products.Since
false rejections are very costly, money will by saved by installing
both systems, instead of either one or the other, and rejecting only
products found flawed by both.
(A) The three percent of flawless products that system X rejects are
not all the same products, piece for piece, that system Y erroneously
rejects.
(B) It is less costly to accept a flawed product than to rejects a
flawless one.
(C) In their price range. System X and Y are the least error-prone
inspection systems on the market.
(D)Whichever system performs the second inspection needs to inspect
only products not rejected by the first system.
(E) Any way of detecting flaw, other than by using either system X or
systemy, requires complete disassembly of the products.
