How can you use a 2s fact and a 1s fact to find 3x8?
3x8 with1s and 2s fact looks like this: =(2x8)+(1x8) =16+8 =24
How can you 2s fact and a 1s fact to find 3x8?
3 = 1 + 2 and 8 = 2+2+2 so 3 X 8 = (1+2)(2+2+2)= (1)(2 + 2+ 2) + (2)(2 + 2 + 2)= 1 X 2 + 1 X 2 + 1 X 2 + 2 X 2 + 2 X 2 + 2 X 2 , so you know the multiplication facts 1 X 2 = 2 and 2 X 2 = 4 and know to add, you can work the problem. 3 X 8 = 2 + 2 + 2 + 4 + 4 + 4 .

What is 22 over 6 as a mixed fraction?
3 2/3 Explanation: 6/6 = 1, so to write 22/6 as a mixed fraction, we find how many 1s we can make from it. 6/6 + 6/6 + 6/6 = 18/6, so that's three 1s. There are 4 sixths left over. 4/6 = 2/3. Three 1s and 2/3 is 3 2/3.
Statistics what is the probality that on five rolls of a fair die you roll three or more 1s?
Since there are 6 numbers (1-6) on each die, and you're rolling it 5 times, the total number of possibilities is 65. You now have to find out, out of the total, how many possibilities fill your requirements. For 5 rolls of one the chance is 1/65. There are 5 possible sets of rolls where you'll get 4 1s (4 1s and a 2, 3, 4, 5, or 6). Lastly there are 25 possible sets of rolls where you'll get 3 1s (3 1s and a 2 and 2 or a 2 and 3 or a 2 and 4 etc). so adding up all the possibilities that is 31/65. That is a percentage of .4% or 4 out of 1000 rolls of all the dice you will get 3, 4, or 5 1s. Sounds like a yahtzee question.
