I am assuming you meant "Roll a sum of 10".
First find all the combinations:
1st dice 2nd dice
4 + 6
5 + 5
6 + 4
Next, calculate the probability of rolling a 4,5, or 6: 3/6 => 1/2 on first dice
Then, calculate the probability of rolling a number on the second dice that adds up with the first number to make 10.
Note: once you roll the first number only 1 other number will make a match, so the probability on the second dice is: 1/6 on second dice
Finally, multiply the two fractions together: 1/2 x 1/6 = 1/12
Your probability is: 1/12 in fraction form, .083 in decimal form, and 8.33% in percent form.
Hope this helps and May the Force Be With You!

Varies jointly means that y is related to the product of x and z:
.. y = k*x*z
.. 64 = k*8*4
.. k = 64/32 = 2
Then for your new numbers,
.. y = 2*7*6
.. y = 84
So is 4 floors / 10 seconds
If you have 60 seconds you can multiple 10 by 6 because 10×6=60
so you also have to multiple 4 by 6
4×6=24
and because it's descending it's 100-24= 76
I am going to say the cheapest would be 65$ would be the answer. Because if you want it to be shipped too you would add 7.25$ to 65$ to what you are paying for. And taking 10 dollars off (subtracting) you would get 62.25$ But if you would take 65$ from you buying it and used the coupon you would have to pay 55$ The cheapest way is to buy that item (the item costs 65$) and use the 10% off coupon.
