Answer:
"p," the probability of success, is the chance of winning a prize. This is equal to 50% (1/2).
1 - p, the probability of failure, is the chance of not winning or losing a prize. This is equal to 50$ (1 - 0.5).
Step-by-step explanation:
When an outcome is obtained from two events, the probability of the outcome happening is 50% (1/2).
On the other hand, the probability of the intended outcome not happening is the difference between 1 and the probability of obtaining the outcome from the two events. This is statistically expressed as 1 - p.

Answer: - 8.89%
I am going to explain you in detail ir order to help you to be able to do this kind of problems by yourself.
The definition of percent change, %, is:
change
% = ---------------- * 100
base value
The base value is from where you start or the value for which you want to asses the variation.
So, in this case the base value is 90 (starting value).
The change is final value - initial value = 82 - 90 = - 8. The negative sign means that the value decreased.
So, following the formula you get:
82 - 90 - 8
% = ----------- * 100 = -------- * 100 = - 8.89
90 90
Answer: the percent of change is - 8.89 %, meaning that the value decreased 8.89%.
