答案 选D要求的是只少有一次偶数的概率.只要用1减去全是奇数的概率就成了.所以是1-(1/2)^3=7/8相关推荐 1概率问题A fair die is thrown three times.Find the probability of getting at least one even number.A. 1/8B. 3/8C. 5/8D. 7/8麻烦请给出过程,谢谢!反馈 收藏 ...
Answer to: Find the probability that at least 90% of the items in a given batch will be acceptable. By signing up, you'll get thousands of...
a single throw of a die Similarly, probability of getting an even number Probability of getting an even number three times Therefore, probability of getting an odd number at least once - Probability of getting an odd number in none of the throws - Probability of getting an even number thrice...
Find the probability of having at least one child of each sex if you have 3 children. Assume P(boy) = P (girl) = 0.5. Independent or Dependent Events: According to the given problem, we first need to define the random variable, and based on ...
The cost-based optimiser has a fixed idea of how likely any given test is to succeed. In some cases the probability takes account of the specific nature of the test (for example,-type fis assumed to be more likely to succeed than-type c). The cost-based optimiser is currently being eva...
Consider the experiment of tossing two fair coins simultaneously, find the probability that both are head given that at least one of them is a head. View Solution A manufacturer produces nuts and bolts . It takes 1 hr of work on machine A and 3 hr on machine B to produce a package ...
Note that at least 90% of the values are below the 90th percentile of the data set. In other words, the 90th percentile tells you what it takes to be in the top 10%. Let’s look at an example to see how it works in Excel. ...
This is the worst part because it means a high probability that your smartphone has been lost or stolen. Don’t despair, maybe you can get it back. For this, it is important to know the IMEI, you can know it even if you do not have the smartphone. ...

For the approximation results (especially for the hypermutation), we had to diverge significantly from Witt's analysis, which relies on a constant upper bound on the probability that the assignment of a constant number of specific jobs to the machines will not be changed for at least a linear...
