1) A balanced die is tosssed six times, and the number on the uppermost face is recorded each time. What is the probability that the numbers recorded are 1, 2, 3, 4, 5, and 6 in any order?
My attempted answer is (6!)/(6^6), is it correct?
2) Suppose a die has been altered so that the faces are 1, 2, 3, 4, 5, and 5. If the die is tossed five times, what is the probability that the numbers recorded are 1, 2, 3, 4, and 5 in any oder?
No clue...can anyone help me, please?
3) We need to arrange 5 math books, 4 physics books and 2 statistics books on a shelf. How many possible arrangements exists so that books of the same subjects will lie side by side?
Is it 3! x (5! x 4! x 2!)?
Thanks for helping!
