Consider the subsets a = {1, 7, 8}, b = {1, 6, 9, 10}, and c = {1, 9, 10}, where u = {1, 2, 10}. (a) list the nonempty minsets generated by a, b, and c. (b) how many elements of the power set of u can be generated by a, b, and c? compare this number with | p(u) |. give an example of one subset that cannot be generated by a, b, and c.

Suppose i flip two identical coins. what is the probability that i get one head and one tail?

Select all of the following expressions that are equal to 2.5.

Consider the following geometry problems in 3-space enter t or f depending on whether the statement is true or false.
