SOLUTION: Put one white ball in the rst urn and the other nine balls in the second urn. This gives a probability of (1=2)1+(1=2)(4=9) = 13=18 of drawing a white ball. In fact, this solution is best if there are n black balls and n white balls, and gives probability (1=2)1+(1=2)n 1 2n 1 = 3n 2 4n 2 of draw-ing a white ball.

Bid on affordable CNC mills at auction The milling machine, or simply mill, is a machine tool for the machining of metal, wood or plastic via chip/layer removal.

The Loesche coal grinding mill range is divided into two serial types: Small twin mills constructed to individual specifications (LM 12.2 D to LM 20.2 D), with table diameters from 1,200 to 2,000 mm. Larger mills with two, three and four rollers and modular struc-tures (LM 21.2 D to LM 43.4 D), with table diameters from 2,100 to 4,300 mm.

Disadvantages of Hammer Mill. 1. Not recommended for the fine grinding of very hard and abrasive material due to excessive wear. 2. Not suitable for low-melting sticky or plastic-like material due to heat generation in the mill head as a result of mill fouling. 3. The mill may be choked if the feed rate is not controlled, leading to damage.
