You have 30 of each of the following type of objects: A, B, C, and D. The objects of each type are identical. In how many ways can you choose a set S of 80 objects? (Each type is identical so it isn't just 120 C 80).
Homework Answers
Let n1, n2, n3 and n4 be the number of objects selected of Type A, B, C and D respectively.
Hence, we have, n1 + n2 + n3 + n4 = 80, where, 0 <= n1, n2, n3, n4 <= 30.
Thus, the number of ways we can choose 80 objects =

Suppose you have six different books on a shelf with labels A, B, C, D, E, and F. (a) In how many different ways can you arrange the books on the shelf? In other words, how many distinct linear permutations of these are possible? (b) In how many different ways can you arrange the books on the shelf if books A, B, and C are grouped together? For example, EBACFD would be an acceptable arrangement, but EBAFDC would not be...

You have a full set (26) of alphabet blocks and you have 50 empty boxes to place them in. (You must place each block into a box.) a. If you think of each box as being different from every other box, how many different ways are there to put the blocks into the boxes if each box is only large enough to accept a single block? b. If you think of each box as being different from every other box,...

Four identical metallic objects carry the following charges: +1.45, +6.97, -4.56, and -9.52C. The objects are brought simultaneously into contact, so that each touches the others. Then they are separated. (a) What is the final charge on each object? (b) How many electrons (or protons) make up the final charge on each object?

200 identical toys are to be sent to 5 families (A, B, C, D, E). If each family must get at least 3 toys and the family “A” cannot have more than 30 toys, how many different ways are there to distribute the toys? (Hints: Do not use the multinomial theorem and start with subtracting 3 from the number of candies from each of the family.)
