Answer:
Step-by-step explanation:
Step 1:
x - > number of Avocado
y -> number of melon
Step 2:
x ≤ 3y
x + y ≥ 20
Step 3:
x + y≥ 20
y ≥ -x + 20
Step 4:
( 1 , 20)
x ≤ 3y ; y≥ -x + 20
1 ≤ 3*20 ; 20 ≥ -1 + 20
1 ≤ 60 ; 20 ≥ 19

<h2>Answer:</h2><h2>The probability of students who play both basketball and baseball = 
</h2>
Step-by-step explanation:
In a certain Algebra class,
The total number of students = 27 students
Let the students playing basketball be represented as A and baseball as B.
The students who play basketball, A= 11
The students who play basetball,B =9
The students who play neither sport, = 11
The students who play both basketball and baseball, = ?
By formula, P(AUB)=P(A)+P(B)-P(A∩B)
Substituting the values in the equation, we get
P(AUB) =
P(AUB) =
The probability of students who play both basketball and baseball =
