Four technicians regularly make repairs when breakdowns occur on an automated production line. Janet, who services 20% of the breakdowns, makes an incomplete repair 1 time in 20; Tom, who services 60% of the breakdowns, makes an incomplete repair 1 time in 10; Georgia, who services 15% of the breakdowns, makes an incomplete repair 1 time in 10; and Peter, who services 5% of the breakdowns, makes an incomplete repair 1 time in 20. For the next problem with the production line diagnosed as being due to an initial repair that was incomplete, what is the probability that this initial repair was made by Tom? Answer in three decimal places

Measuring carpentry and miscellaneous items

The modification of planning and drawing of the construction project into the various descriptions and quantities to estimate the value, cost, and price of the project is known as measurement. The quantity supervisor produces the details of the quantities to the contractor or subcontractor to measure the cost of the work and determine the profit of the contractor or subcontractor. The measurement of the construction work depends on its type, usage, and stages in the project. In the early stage of the project, the details of the project depend on the general parameters. As the work starts, more information is searched and the details are dependent on the elemental estimates of the work.
