First, calculate the reduction of the price
reduction = normal price - sale price
reduction = 57 - 41.6
reduction = 15.4
The price decreased £15.4

Second, change the reduction of the price into percentage
percent = reduction/normal price × 100%
$percent= \frac{15.4}{57}\times100$ %
$percent= \frac{15.4\times100}{57}$ %
$percent= \frac{1540}{57}$ %
percent = 27.01%

The percentage reduction is 27.01% or approximately 27%

<h3>What is Normal Probability Distribution?</h3>

The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:

$z=\dfrac{x-\mu}{\sigma}$

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.

The mean and the standard deviation are given, respectively, by:

$\mu = 65\ \ \sigma= 3.5$
