What are the combinations of rolling 2 dice?
In a combination the order does not matter, so they are: 1 1 , 1 2 , 1 3 , 1 4 , 1 5 , 1 6 2 2 , 2 3 , 2 4 , 2 5 , 2 6 3 3 , 3 4 , 3 5 , 3 6 4 4 , 4 5 , 4 6 5 5 , 5 6 6 6
What is the probability of getting 3 sixes in 5 tosses of a die?
125/3888 or 3.22%.A shortcut can be taken instead of the traditional tree-method or combination counting:Assume that there are 5 "spots" in which the 3 sixes can be placed. Using the nCr probability formula, we find that there are 10 different arrangements of 3 sixes in 5 spots. (5!/((5-3)!*3!)). This simplifies to (5*4)/2, which is 10.A visual of this:6-6-6-X-X6-6-X-6-X6-6-X-X-66-X-6-6-X6-X-6-X-66-X-X-6-6X-6-6-6-XX-6-6-X-6X-6-X-6-6X-X-6-6-6Next, all we need to do is figure out how many different combinations of each of the above combinations there are. Since there are only two variable numbers (denoted X) in each combination, and each can only be an integer from 1-5, we can determine that for each combination above there are 25 subsequent combinations (5^2).Finally, (10*25)/(6^5) = 125/3888.
