The characteristics of a population that a random variable represents are 1. <u>As many as you wish</u> and 4. <u>Two or more</u>.
<h3>What is a random variable?</h3>
A random variable is a variable with unknown outcomes.
A random variable can have either discrete or continuous values.
It is discrete when it has specific values. It is continuous when it assumes some continuous values.
Thus, the characteristics of a population that a random variable represents are 1. <u>As many as you wish</u> and 4. <u>Two or more</u>.

There were 37 student tickets and 52 adult tickets
Step-by-step explanation:
Let x be the number of student tickets and y be the adult tickets
Then
According to given statement that total 89 tickets were sold
x+y=89 Eqn 1
And
$5 for an adult ticket and $3 for student ticket ,and total cost $371
3x+5y=371 Eqn 2
From eqn 1
Putting in eqn 2
Subtracting 267 from both sides
Dividing both sides by 2
Putting y=52 in eqn 1
Hence,
There were 37 student tickets and 52 adult tickets

Answer:
50% of rolling an even number.
33.33% of rolling a number greater than 4.
Step-by-step explanation:
<h2><em>Even Number Probability: </em></h2>
There're three possibilities to roll an even number: 2, 4, and 6. If it's a six sided dice, there're a total of six rolling possibilities, so the ratio is 3:6, 1:2, or 50% chance of rolling an even number.
<h2><em>
Greater Than Four Probability:</em></h2>
There're only two number greater than four on a traditional six sided dice: 5 and 6. There're, again, six sides on a six sided dice, so the ratio of rolling a number greater than four is 2:6, 1:3, or 33.33%.
