Problem 1 - Brinell E Rockwell El Bookmark this page Test clue Jul 2?, 202212200 {33 Brinell 8. Rockwell D.Dl'2. points [gradedl Brinell s Rockwell lBaRl is a high-end manufacturer of cutting and drilling bits for lathe machines, drill presses, and other metalworking equipment. They pride themselves in producing only pits of the 1.rery best quality, guaranteed to last longer than the bits from any of their competitors. Brinell S. Rockwell has a hotline where customers can call to report when a BEIR bit fails before it is expected. At that time, Brinell E. Rockwell will ship a replacement pit to the customer free of charge, and the customer will return the failed pit for examination. Back at the Quality Control Department of Brinell E: Rockwell, a team of scientists and engineers including seyeral with PhDs in Metallurgy will examine the failed bits under the microscope, ill-Ray machines, and other diagnostics equipment to determine exactly what went wrong. Brinell 3. Rockwell's quality control team keeps the failed bits that they haye collected from customers in large glass containers, using one glass container per hit model. They haye gathered thousands of failed drilling and cutting bits of ?3 different models, including 62 models of drilling bits. These F32 models of drilling bits can be grouped into four families: Diamond Bits Tungsten Bits Iridium Bits Ademanlium Bits 14 1Q 20 Q In summary, they hate collected failed bits of ?3 different models, and they use one glass container for every hit model. Therefore, Brinell 8. Rockwell has in the lab a total of ?3 different glass containers. Taking into account that drilling bits can be grouped into families, we know that 14 glass containers contain Diamond bits, 19 glass containers contain Tungsten bits, 20 glass containers contain Iridium bits, and 9 glass containers contain Adamantium bits. Part 1 Donald Walker is the first worker to arriye to the lab. Following the standard policy of Brinell S. Rockwell, he will pick up the first bit to be inspected from a randomly selected glass container. This means he is equally likely to pick up a bit from any one of the 1'3 containers. What is the probability that Donald will pick up an Iridium bit? Enter your answer as a fraction or in decimal form using three decimal places. For example, if your answer is seeds. you should enter .232 it the box below or the respective fraction. Submit Save You hays used D of 15 attempts

Problem 1 - Brinell & Rockwell Bookmark this page Test due Jul 27, 2022 12:00-03 Brinell & Rockwell 0.0/2.0 points (graded) Brinell & Rockwell (B&R) is a high-end manufacturer of cutting and drilling bits for lathe machines, drill presses, and other metal-working equipment. They pride themselves in producing only bits of the very best quality, guaranteed to last longer than the bits from any of their competitors. Brinell & Rockwell has a hotline where customers can call to report when a B&R bit fails before it is expected. At that time, Brinell & Rockwell will ship a replacement bit to the customer free of charge, and the customer will return the failed bit for examination. Back at the Quality Control Department of Brinell & Rockwell, a team of scientists and engineers - including several with PhDs in Metallurgy - will examine the failed bits under the microscope, X-Ray machines, and other diagnostics equipment to determine exactly what went wrong. Brinell & Rockwell's quality control team keeps the failed bits that they have collected from customers in large glass containers, using one glass container per bit model. They have gathered thousands of failed drilling and cutting bits of 73 different models, including 62 models of drilling bits. These 62 models of drilling bits can be grouped into four families: Diamond Bits Tungsten Bits Iridium Bits Adamantium Bits 14 19 20 9 In summary, they have collected failed bits of 73 different models, and they use one glass container for every bit model. Therefore, Brinell & Rockwell has in the lab a total of 73 different glass containers. Taking into account that drilling bits can be grouped into families, we know that 14 glass containers contain Diamond bits, 19 glass containers contain Tungsten bits, 20 glass containers contain Iridium bits, and 9 glass containers contain Adamantium bits. Part 1 Donald Walker is the first worker to arrive to the lab. Following the standard policy of Brinell & Rockwell, he will pick up the first bit to be inspected from a randomly selected glass container. This means he is equally likely to pick up a bit from any one of the 73 containers. What is the probability that Donald will pick up an Iridium bit?
