<h3 /><h3>System of equations</h3>
Given the following parameters
Ethan's score = x points
His younger sister's score = 8 points
If their total score is y points, hence the equation relating x and y is expressed as:
x + 8 = y
x = 8 - y
If x = 10
y = x + 8
y = 18
The ramining values will be<u> 19, 20, 21, 22 and 23</u>

Answer:
9/23
Step-by-step explanation:
Of the 23 students, 9 play both baseball and basketball. The probability of choosing one of those is 9/23.
___
Let A represent basketball, and B represent baseball. Then ...
P(A or B) = P(A) +P(B) -P(A and B)
Since 8 students play neither sport, we have ...
1 -8/23 = 11/23 +13/23 -P(A and B)
15/23 = 24/23 -P(A and B)
P(A and B) = (24 -15)/23
P(A and B) = 9/23
