Final answer:
A safety committee should meet as frequently as needed to address the unique conditions and risks of each workplace. There's no one-size-fits-all answer, but rather it depends on the industry and nature of the work. Legal requirements may also dictate meeting frequency.
Step-by-step explanation:
The frequency at which a safety committee should meet can vary based on company policy, the nature of the workplace, and any applicable legal requirements. However, there isn't a universal rule for all safety committees. To assess how often a safety committee should meet, it's important to consider the specific needs of the organization and the role of the committee. For example, if the context is similar to the provided information about the Congress meeting annually, a safety committee in a low-risk office environment might meet quarterly, while in a high-risk industry, monthly or even weekly meetings may be more appropriate. The key is to ensure that the safety committee meets frequently enough to effectively oversee the company's safety programs and respond to issues as they arise.
In terms of finding the probability that the safety engineer will have to examine at least three reports to find an accident caused by employee failure, the probability that their first report details such an accident is 0.35. From this, one could calculate the probability of needing to review multiple reports until finding one with the desired information. As for how many reports the safety engineer would, on average, expect to look at before finding what they are searching for, one could use the concept of expected value in probability theory to find this figure.
