EXPERTS ONLY its not 0 or 128 In how many ways can you put seven marbles in different colors into four jars? Note that the jars

KonstantinChe [14]

Answer: 16384

Step-by-step explanation:

Given, Total jars = 4

Total marbles = 7

Since we need to put marbles in 4 different jars, we need to choose a jar each time.

Possible choices for jars =4

Number of time we need to choose = number of marbles

So, by fundamental counting principle, we have

Total ways to put 7 marbles in 4 jars = $4\times4\times 4\times 4\times4\times 4\times 4$

$=4^7\\\\=16384$

Hence, the required number of ways =16384

6/10 x 10/1
6 x 10 = 60
10 x 1 = 10
60/10 = 6

1/2 x 10/1
1 x 10 = 10
2 x 1 = 2
10/2 = 5

3/4 x 20/1
3 x 20 = 60
4 x 1 = 4
