-2(a - 8) + 6a = 36
-2(a) + 2(8) + 6a = 36
     -2a + 16 + 6a = 36
     -2a + 6a + 16 = 36
              4a + 16 = 36
                    - 16  - 16
                       4a = 20
                        4      4

Using the normal distribution, the areas to the left are given as follows:
a) 0.7910.
b) 0.6664.
c) 0.3707.
d) 0.8508.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean  and standard deviation
 and standard deviation  is given by:
 is given by:

- The z-score measures how many standard deviations the measure is above or below the mean. 
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X, and is also the area to the left of Z.
Hence:
- The area to the left of Z = 0.81 is of 0.7910.
- The area to the left of Z = 0.43 is of 0.6664.
- The area to the left of Z = -0.33 is of 0.3707.
- The area to the left of Z = 1.04 is of 0.8508.

The actual probability of having odd is 3/6=1/2
so no of odds theoretically is 250
but it is 325 
so, experimental is higher than theoretical 
so answer is B ! 
and you can go for that !
