Suppose that three computer boards in a production run of forty are defective. A sample of five is to be selected to be checked for defects. a. How many different samples can be chosen? b. How many samples will contain at least one defective board? c. What is the probability that a randomly chosen sample of five contains at least one defective board?
If the largest of 56 consecutive integers is 279 , what is the smallest?
Two new drugs are to be tested using a group of 60 laboratory mice, each tagged with a number for identification purposes. Drug \(A\) is to be given to 22 mice, drug \(B\) is to be given to another 22 mice, and the remaining 16 mice are to be used as controls. How many ways can the assignment of treatments to mice be made? (A single assignment involves specifying the treatment for each mouse-whether drug \(A\), drug \(B\), or no drug.)
a. How many ways can three of the letters of the word \(A L G O R I T H M\) be selected and written in a row? b. How many ways can six of the letters of the word ALGORITHM be selected and written in a row? c. How many ways can six of the letters of the word ALGORITHM be selected and written in a row if the first letter must be \(A\) ? d. How many ways can six of the letters of the word ALGORITHM be selected and written in a row if the first two letters must be \(O R\) ?
