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.
The probability of getting heads is 1/2 or 0.5 and the probability of failure is 0.5 or 50%.
It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
Win a prize if it comes up heads.
p(getting heads) = win prize
Number of outcomes = {H, T}
Total number of outcomes = 2
Favourable outcomes = {H}
Number of favourable outcomes = 1
p(getting heads) = 1/2 = 0.5
The complement probability of the above event:
= 1 - p
= 1 - 0.5
= 0.5 or 50%
The above probability represents the chances not getting head or probability of failure.
Thus, the probability of getting heads is 1/2 or 0.5 and the probability of failure is 0.5 or 50%.
