Answer:
1320
Step-by-step explanation:
There are three "spots" for balls.
__ __ __
For the first "spot," and without replacement, meaning we don't put the balls back, there are 12 choices.
12 __ __
But for the next spot, there are only 11 choices. And for the next, there are only 10!
12 11 10
Since these are independent events, we multiply them together.
12 x 11 x 10 = 1320
There are 1320 possibilities!
How could we do it on the calculator, much faster? The question says "in order," so we know it's a <em>permutation,</em> not a <em>combination.</em> This is the nPr button on the calculator (math -> prb -> 2). Just type in 12 nPr 3 and you get the same answer, 1320.
Answer: 7 hours left!
Step-by-step explanation:
She had used up 12 hours and 45 minutes. 7 hours and 15 minutes left, but if you're including the minutes, then it's 7 hours and 15 minutes. Good luck! :D

Answer:
exactly 10: 8.33 %
at least 10: 16.66 %
Step-by-step explanation:
first we have to see the amount of favorable results
4+6 = 10
6+4 =10
5+5=10
then we have to see the amount of possible results
Each dice has 6 faces and there are 2 dice, so if we make 6 ^ 2 we will get the number of possible combinations
6^2 =
6*6 = 36
Now we only do the number of favorable results on the possible results and multiply it by 100 and obtain the probability
100*3/36 = 8.33 %
we do the same for those greater than or equal to 10
4+6 = 10
6+4 = 10
5+5 = 10
6+5 = 11
5+6 = 11
6+6 = 12
100*6/36 = 16.66 %
