A four-sided die is rolled repeatedly, until the first time (if ever) that an even number is obtained. What is the sample space
Andrew [12]

Answer:

Sample space by its definition is termed as the list of all the possible outcomes of an experiment.

Therefore, the sample space for this experiment rolling a four-sided die will be: {1, 2, 3, 4}

Step-by-step explanation:

When you roll a a four-sided die, number of dots on uppermost face is said to be an outcome.

For example,  whenever a four-sided die is rolled we can get either 1, 2,3 or 4 dots on the upper most face as an outcome.

As we know that rolling a four-sided die will bring the following possible outcomes: {1, 2, 3, 4}

Possibilities of the number being even (2 and 4) = 2

Probability of the number being even = 2/4 = 1/2

Sample space by its definition is termed as the list of all the possible outcomes of an experiment.

As we have already determined that rolling a four-sided die will bring the following possible outcomes: {1, 2, 3, 4}

Therefore, the sample space for this experiment will be: {1, 2, 3, 4}

Keywords: sample space, 4-sided dice

Answer:

<em>The sister's age is 8 and the brother's age is 4</em>

Step-by-step explanation:

Let's make:

x = age of the brother

y = age of the sister

x - 2 = age of the brother two years ago

y - 2 = age of the sister two years ago

Two years ago, the age of the sister was three times greater than the age of the brother:

y - 2 = 3(x - 2)

Now, the relation doubles:

y = 2x

Substituting in the first equation:

2x - 2 = 3(x - 2)

Operating:

2x - 2 = 3x - 6

Subtracting 3x -2:

2x - 3x = 2 - 6 = -4

Solving:

x = 4

y =2x = 8

The sister's age is 8 and the brother's age is 4
