Sets I andB are defined as follows. I={d,f, k} B={b, c,f} Answer each part below. Write your answer in roster form or as Ø. (a) Find the intersection of I and B. 00... InB%3= (b) Find the union of I and B. IUB = || 產

Write ALWAYS if the statement is always true, SOMETIMES if it is sometimes true, sometimes false, and NEVER if it is never true. The set {0} is a singleton. I

Using the variable x, write the interval (3,9] using set-builder notation. (3,9]= {x|__}

Each time a component is tested, the trial is a success (S) or failure (F). Suppose the component is tested repeatedly until a success occurs on three consecutive trials. Let Y denote the number of trials necessary to achieve this. List all outcomes corresponding to the five smallest possible values of Y. (Enter your answers in set notation.)   what is the answer for Y=7.    I have {SFFFSSS,SSFFSSS,FFFFSSS,FSSFSSS,FSFFSSS. Are there more?

Fill in the blanks in the following sentence: If A and B are any sets, then by definition of set difference x € A-B if and only if and
