The probability that the sample proportion is less than 0.80 is mathematically given as P(z<-0.52)
<h3>What is the probability that the sample proportion is less than 0.80?</h3>Generally, the equation for probability is mathematically given as
p=82/100
Therefore
p=0.82
q=1-p
q=1-0.82
q=0.18

As a property of equations, you can add or subtract the same quantity to/from both sides, and the truth value of the equality will remain the same: if you start with something true, e.g. 7=7 and add the same quantity to both sides, e.g. 7+4=7+4, you will still have something true, i.e. 11=11.
On the other hand, if you start with something false, e.g. 3=7 and add the same quantity to both sides, e.g. 3+6=7+6, you will still have something false, i.e. 9=13.
So, you can subtract from both sides to transform the equality into
as required.
