Artemon [7]

Answer:

a) 0.383

b) 0.375

Step-by-step explanation:

a) Calculate each z-score.

z = (x − μ) / σ

z₁ = (112 − 118) / 12 = -0.5

z₂ = (124 − 118) / 12 = 0.5

Use a calculator or z-score table to find the probability.

P(-0.5 < Z < 0.5) = 0.6915 − 0.3085 = 0.383

b) 0.383 × 16 ≈ 6. So the expected proportion would be 6/16 = 0.375.

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