The viewer mistakenly determined that one of the equations in the system should be 2 x + y = 28. Instead modifications should have been made before applying the equation.
<h3>What is an Equation ?</h3>
An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.
Total Questions = 20
Total Points = 28
Correct Answers = +2 points
Incorrect Answers = -1 point
The viewer represents the correct answers with x and the incorrect ones with y.
x+y = 20
for every correct answers 2 points;
and for every incorrect answers, -1 point
This can be written as
2x-y = 28
The viewer's mistake is that; instead of subtracting total incorrect points from the correct points, the viewer added them together;
now
2x-y = 28
x+y = 20
On adding the equations
]3x = 48
x = 16
y = 4
This means that the contestant answered 16 questions correctly and 4 questions incorrectly
The viewer mistakenly determined that one of the equations in the system should be 2 x + y = 28.

Answer:
The probability of getting at least one hit in 5 games is 0.772
Step-by-step explanation:
The correct question is as follows;
One interpretation of a baseball player's batting average is as the empirical probability of gettig a hit each time the player goes to bat. If a player witt a batting average of 0.256 bats 5 times in a game, and each at-bat is an independent event, what is the probability of the player getting at least one hit in the game?
We proceed with the answer as follows;
Here, we want to calculate the probability of a player with a certain batting average getting at least one hit in a game if he bats 5 times
Mathematically, Probability of getting at least one hit in 5 games = 1 - Probability of getting no hit in 5 games
Let p = probability of getting hit in a game = 0.256
q = Probability of getting no hit in a game = 1-0.256 = 0.744
So the probability of getting no hits in 5 games will be 0.744^5 = 0.228
Thus, the probability of getting at least one hit in the 5 games = 1 - 0.228 = 0.772
