sorry i know this BOB is late but i totally forgot to do it i got caught up studying after work and i just remembered. but anyways.. ok so after today's class talking about permutations and combinations i think i fully get that stuff.. and well for the kinds of questions like "how many different 4 digit numbers are there in which all the digits are different?" i think i am ok with but when it came to today's pretest.. i blanked out on the second page.. the question about Peter and Deanna.. i got lost... but after looking over today's slides i think i got it down i just hope i don't blank out tomorrow onthe actual test. i know it's late but i think i am going to keep studying till maybe 2 or 2:30 because i really want to do well on this test!

goodluck dudes!
