Answer the following: p = {a, b,c, f,h} and q = {a, c,d, e,g, i} find: a. p intersection qb. p union qc. n(p intersection q)d. n(p union q)

The intersection of two sets and is the set of all elements belonging to both and .

So, in this case, the intersection between and , which we write as , is the set

The union, which we write as , is the set of the elements belonging to at least one of the sets without repetitions. So, you can simply list one set and add the elements of the other which didn't already belong to the first one:

Finally, with we indicate how many elements belong to , so you can simply count them:

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
