Answer:
<h3>There's a probability of 0.60 to select a student that owns an Android Phone or has service with AT&T.</h3>Step-by-step explanation:
The image attached shows the Venn Diagram.
From the diagram, 12 students use AT&T service and 6 students use an Android phone only. The total number of students is 30.
The probability to pick a student with Android is
The probability to pick a studen with AT&T is
Remeber, the probability of one event OR another implies the sum of probabilities.
Therefore, there's a probability of 0.60 to select a student that owns an Android Phone or has service with AT&T.

Answer:
Step-by-step explanation:
It is given that the regression equation
predicts an adult’s height (y) given the individual’s mother’s height (x1), his or her father’s height (x2), and whether the individual is male (x3 = 1) or female (x3 = 0).
The coefficient of x1 = 0.32 represents the increase in height of the child due to one inch increase in mother.
Similarly coefficient of x2 = 0.42 represents the increase in height of the child due to one inch increase in father.
and coefficient of x3 = 5.31 represents the increase in height of the child due to being a male than a female.
