1) When randomly ordering the letters A, B, C, D, and E from left to right, what the is probability that the first three on the left with be, in order, A B C. show how to solve.
2) Suppose 3 letters will be randomly selected from A, B, C, D, and E. what is the probability that the 3 letters chosen are A, B, and C?
3)Suppose that 3 balls will be randomly put into 3 buckets, with each ball being equally likely to be put into each of the buckets, independently of which buckets are chosen for any of the other balls. What is the probability that all of the balls will be put into the same bucket?
4)suppose that 3 balls will be randomly put into 3 buckets, labeled 1, 2, & 3, with each ball being equally likely to be put into each of the buckets, independently of which buckets are chosen for any of the other balls. What is the probability that at least one ball will be put into bucket 3?
5) Suppose that 3 balls will be randomly put into 3 buckets, labeled 1, 2, & 3, with each ball being equally likely to be put into each of the buckets, independently of which buckets are chosen for any of the other balls. What is the probability that each of the buckets will have one ball put into it?
