Hockey Sticks For Sale
Math help, please !!!!!!!!!!!!!?
The manufacturer makes hockey sticks and wood composites. Batons Hockey wood represent 80% of total sales. Because defects, 10% of hockey sticks of wood and 25% of combinations of compounds must be replaced. If a hockey stick is chosen at random, what is the probability that it is defective. A. 0.13 b 0.14 C. 0.15 m. 0.175 I have no idea how to get the answer can show me how was the answer.
The answer should be 0.13. To solve this, you must determine the percentage of strips of wood and composites. He said that 80% of wooden sticks, leaving the remaining 20%. Since the company has only composite sticks and wood, and 80% wood, 20% of clubs is to be composed. Now we have 8 = W (= 80% wood) and .2 = C (20% = Composite) Since we have the percentages of clubs actually allowed to use these values with defect rate find the posttest probability. For wooden sticks: 10% of all wooden poles that are defective. All wooden sticks that are equal to 80% of manufacturer's products. Thus, 10% of the original 80% (0.1 * 0.8) would amount defective products, has wooden stick. 0.1 * 0.8 = 0.08, which is the probability of selecting a defective stick of wood. For compounds Cartridge: 25% of all composite sticks are actually defective. All composite stick equal to 20% of manufacturer's products. Thus, 25% of the original 20% (0.25 * 0.2) is the quantity of defective products, composite stick made. 0.25 * 0.2 = 0.05, which is the probability of selecting a defective composite stick. We now have the chance to find a stick of defective wood, and the probability of hit compound defective. For find the total probability of finding a defective stick regardless of their type (which means it can be wood or mixed) must add 0.08 and 0.05 all (the probability of finding a stick of wood + deficient in the probability of finding a defective composite stick), equivalent to 0.13. By Therefore, the final answer is 0.13. Hope this helps! If no explanation is required, it only mentioned in your question or send a message.
