Answer 5

question number 3 explanation... you are being asked about the order in seeing the movies, as in you have a choice of 12 for the first movie, and after you see that first movie, there are 11 left for your choice of your second movie. Then you have 10 left for your 3rd, etc. So, the number of orders is 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 so you would multiply those out. There is a slightly shorter way to get the answer and that is with factorial notation. Your answer is 12! divided by 4! Those "1" mean you multiply the number by successively smaller integers until you get to 1. So, 5! = 5 x 4 x 3 x 2 x 1.... so option number "A" is correct for this question....

Answer 6

are 4 and 5 right?

Answer 7

For the 4th question, you don't care about the order of the toppings, you are concerned about the "group of 3" toppings taken all at the same time and in no particular order. So, that would be 13C3 or "13 combination 3" which is 13! divided by (10! times 3!)... it will be 286.. so option "D" for the forth one is correct...

Answer 8

the 5th question is very sipmle... it will be 9C7... 36... so option "D" works here... @heydoe
