I wanted to see if I was correct with these three questions:
1) You have 5 identical boxes that stand one after another. How many different ways can you put your 3 identical eggs into these boxes?
I found a few different answers for this one. You have 3 identical eggs and 4 possible ways of putting 3 eggs into a box (0, 1, 2, or 3). And with 5 identical boxes, would this mean a total of 100 different ways?
2) How many ways can the letters of the word "YUSSUF" be arranged?
For this one, I got an answer of 30 different ways. You 6 total letters and a full total of 720 different rearrangements. Then, you have two letters that are the same so 4 different letters and 24 different ways. Then in dividing the total number of possible rearrangements by 24 real combinations, you'd get an answer of 30.
3) A soccer team includes 18 players. On the field, there should be only 11 players for that team. How many different groups of 11 players can the coach choose?
I had no idea on that last one...
