kisha has five different marbles. How many d
ifferent ways can she place the marbles into two bags so that at least one marble is in each bag
pick a bag: 2 ways
Put at least 1 marble in the bag:
Note: each of the 5 marbles is either in or not in the 1st bag: 2^5 = 32 ways
But the bag cannot have 0 marbles and cannot have all 5 marbles.
2^5-2 = 30 ways
Ans: 2*30 = 60 ways
