The mistake in Kevin's calculation is when calculating P(Red or Green).
He considered only one section instead of both sections
<u>The correction is:</u>
<em />
<em>Since, there are 2 green sections and 2 red sections.</em>
The equation becomes
And the number of times is:
114 divided by 6 equals 19.
Using the normal distribution, it is found that the correct option is:
In a <em>normal distribution</em> with mean 
and standard deviation 
, the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
In this problem:
- The mean on the Wechsler Scale is of 100, hence
.
- The standard deviation is of 17, hence
.
- Brianna had an score of 117, hence
Then:
Hence, the option d is correct.
