OK, so for this equation, your goal is to get the d, and ONLY the d, on one side of the equation. So, to start out, you need to multiply the entire equation, meaning both sides, by 8 because we are trying to get rid of those pesky fractions.
8(1/8(3d-2)=1/4(d+5))
The equation then turns into this because the 8 and 4 cancelled out with the 8.
1(3d-2)=2(d+5)
Now, we need to distribute the left over numbers into the parenthesis.
3d-2=2d+10
And finally, we need to get the d's on one side, and the numbers on the other, so we subtract 2d from both sides and add the 2 to both sides. They then cancel out to make
d=12
Hope it helps! :)

Answer:
X=1, P = 0.091
X=2, P = 0.124
X=3, P = 0.115
X=4, P = 0.378
X=5, P = 0.264
X=6, P = 0.028
Step-by-step explanation:
To calculate the probability distribution of X, first we have to define the sample space.
In this case X=1,2,3,4,5,6. This are the values that X can take.
The probability is calculated as equal to the relative frequency of each of the values.
For X=1, P = 364/4000 = 0.091
For X=2, P = 496/4000 = 0.124
For X=3, P = 460/4000 = 0.115
For X=4, P = 1512/4000 = 0.378
For X=5, P = 1056/4000 = 0.264
For X=6, P = 112/4000 = 0.028
The answer is 37.524 my friend
