If a normal random variable has mean of 0 and standard deviation of 1, it is called a standard normal distribution.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
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.
For the standard normal distribution, the mean and the standard deviation are given, respectively, by:

1/8 because if u were to do that with a whole piece of bread it would equal 1/4 and 1/4 cut in half is 1/8
42% = 210 so,
42/100=210/x
Cross multiply-
42x=21000
Divide by 42 on both sides and you get- 500
It adds .8 for every 1 so it would be 6.2 and 7
