34% because every time you roll the dice each side has a probability of 17%, so since there are numbers 5 and 6 you want to roll, there is a 34% you will get those numbers. the first roll doesn't have an affect on your next roll
Ok, if you roll the dice once - you'll get: 1, 2, 3, 4, 5 or 6. If you roll it twice, you can get one of these combinations: 1,1 - 1,2 - 1,3 - 1,4 - 1,5 - 1,6 2,1 - 2,2 - 2,3 - 2,4 - 2,5 - 2,6 3,1 - 3,2 - 3,3 - 3,4 - 3,5 - 3,6 4,1 - 4,2 - 4,3 - 4,4 - 4,5 - 4,6 5,1 - 5,2 - 5,3 - 5,4 - 5,5 - 5,6 6,1 - 6,2 - 6,3 - 6,4 - 6,5 - 6,6 Here there are 36 combinations in total. Your chance of getting a 5 and a 2 is 1/36. 5,2 only appears once in this list of possible combinations. 2,5 doesn't count (as 2 would come up first).
Answer: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : x-(3*x^3+8*x^2+5*x-7)=0 Step by step solution :Step 1 :Equation at the end of step 1 : x-((((3•(x3))+23x2)+5x)-7) = 0 Step 2 :Equation at the end of step 2 : x - (((3x3 + 23x2) + 5x) - 7) = 0 Step 3 :Step 4 :Pulling out like terms : 4.1 Pull out like factors : -3x3 - 8x2 - 4x + 7 = -1 • (3x3 + 8x2 + 4x - 7) Checking for a perfect cube : 4.2 3x3 + 8x2 + 4x - 7 is not a perfect cube Trying to factor by pulling out : 4.3 Factoring: 3x3 + 8x2 + 4x - 7 Thoughtfully split the expression at hand into groups, each group having two terms : Group 1: 3x3 - 7 Group 2: 8x2 + 4x Pull out from each group separately : Group 1: (3x3 - 7) • (1) Group 2: (2x + 1) • (4x)
3/8 as a percentage is 37.5% and that is rounded to 38%! :) 37% is close but it is not rounded making it not the best estimate, therefore it is not correct.
