Art [367]

Answer:

0.75

Step-by-step explanation:

P(A | B) = P(A and B) / P(B)

P(vanilla | sundae) = P(vanilla and sundae) / P(sundae)

P(vanilla | sundae) = 0.15 / 0.2

P(vanilla | sundae) = 0.75

In a certain Algebra 2 class of 27 students, 11 of them play basketball and 9 of them play baseball. There are 11 students who p

grigory [225]

<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 = $\frac{4}{27}$
