Suppose that 5 identical red wooden blocks and 6 identical white wooden blocks are to be stacked, one on top of another, to form one tall tower of blocks. how many different colour patterns can result?

462

Step-by-step explanation:

Firstly, we will calculate the number of ways we can arrange total number of wooden blocks. Lets say each of them are independent, so altogether we have blocks. And number of ways to arrange 11 blocks would simply be: .

Now, we need to figure out the number of ways 5 red wooden blocks can be arranged, it is and the number of ways 6 white wooden blocks can be arranged is . These are the ways they can be arranged in themselves.

So, we can now find how many different colour patterns can result by:

So in this case it is:

Therefore, there could be 462 colour patterns.

180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
