write my assignment 1343

You’re at the library to do research for your statistics project. You need 5 sources. There

are 7 finite mathematics sources and 11 statistics sources to choose from. Order doesn’t matter.

(a) How many ways can 5 sources be randomly selected out of the 18 sources? Show work.

(b) How many ways can 5 sources be chosen, if 2 must be finite math and 3 must be statistics?

Show work.

(c) Using your answers to parts (a) and (b), if 5 sources are randomly selected from the 18 sources, what is the probability that 2 are finite math and 3 are statistics? Round answer to nearest ten-thousandth (4 places after decimal). Show work.
