<h2>Answer:</h2><h2>The probability of students who play both basketball and baseball =  \frac{4}{27}</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) = \frac{11}{27} + \frac{9}{27} - \frac{16}{27}

 P(AUB) = \frac{4}{27}

The probability of students who play both basketball and baseball =  \frac{4}{27}

Answer:

\frac{11x}{3y}

Step-by-step explanation:

\frac{7x}{3y} + \frac{12x}{9y}

Make both a single fraction by adding together.

\frac{3(7x) + 1(12x)}{9y}

\frac{21x + 12x}{9y}

\frac{33x}{9y}

Simplify

\frac{3(11)x}{3(3y)}

\frac{11x}{3y}
