You roll 2 dice. What is the probability that the sum of the dice is greater than 6 and 1 die shows a 2? A 6 X 6 table of dice outcomes will help you to answer this question
\[\left[\begin{matrix} -& 1 & 2 & 3 & 4 & 5 & 6 \\ 1& 2 & 3 & 4 & 5 & 6 & 7 \\ 2& 3 & 4 & 5 & 6 & 7 & 8\\3& 4 & 5 & 6 & 7 & 8 & 9 \\4& 5 & 6 & 7 & 8 & 9 & 10\\5& 6 & 7 & 8 & 9 & 10 & 11\\6& 7 & 8 & 9 & 10 & 11 & 12\end{matrix}\right]\]
I answered your question...
the first row is the values for the 1st die, the first column is the values for the 2nd die
ow my eyes!!
the inside consists of the sum of dice, so find all values greater than 6, then of those, take the ones with a value of 2 one of the die
the chart confuses me :(
skittles this question has already been answered in my page look aty my page im takeing the same course
shows a 2 are these; 1 2 3 4 5 6 1 x 2 x x x x x x 3 x 4 x 5 x 6 x now we need to account for those that are greater than 6 1 2 3 4 5 6 1 2 x x 3 4 5 x 6 x if i did it right
@curry. im doing this for apex to make up for algebra 2 semester 2. @amister. so i just add all them up and i ge the answer?
The sum of numbers can be either even or odd.... The probability of having a sum as odd is 1/2. Probability of none of the dices showing a four is (5/6)*(5/6) = 25/36 Thus probability of at least one four is 1 - 25/36 = 11/36 Total probability = 1/2 + 11/36 = 29/36
yep; there are 4 ways to get a sum greater than 6 AND one of them is a 2 4/36 = 1/9 right?
got it. thx amistre. new questoin coming up
another way to do this is just create the sample space and weed out the offending options: 11 21 31 41 51 61 12 22 32 42 52 62 13 23 33 43 53 63 14 24 34 44 54 64 15 25 35 45 55 65 16 26 36 46 56 66 delete everything that doesnt have 2 21 12 22 32 42 52 62 23 24 25 26 now delete everything that sums to 6 or less 52 62 25 26 and thats it; 4 left out of 36
