The faces of a tetrahedron die are numbered 1 to 4. if each of the 4 sides is equally likely to land down, what is the probabili
Hoochie [10]

The probability distribution for the face landing down =  4/15

<h3>What is the probability?</h3>

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

<h3>According to the given information:</h3>

If we assign 1 probability x

then 2 has probability  1/2 x.

Similarly,

then 3 has probability = 1/2((1/2)*x) = (1/4)*x

so

then 4 has probability = 1/2((1/4)*x) = (1/8)*x

These probabilities need to sum to 1.

Hence:

                x+\frac{1}{2} x+\frac{1}{4} x+\frac{1}{8} x=1

or equivalently

                   (15/8)*x = 1

                       x = 8/15

the probability distribution for the face landing down  = (1/2)*(8/15)

                                                                                         = 8/30

                                                                                         =  4/15

I understand that the question you are looking for is:

A tetrahedral die has four faces, numbered 1-4. If the die is weighted in such a way that each number is twice as likely to land facing down as the next number (1 twice as likely as 2, 2 twice as likely as 3, and so on) what is the probability distribution for the face landing down?

If f(x) = x^2-1 which of the following ordered pairs would be on the graph of f(x)
Alex Ar [27]

These following ordered pairs are on the graph:

  • (0,1)
  • (5, 24)
  • (-2,3)

-------------------------------

An ordered pair (x, f(x)) will be on the graph if replacing them into the equation, we get an equivalence.

-------------------------------

The equation is:

f(x) = x^2 - 1

-------------------------------

(0,1)

Here, we test x = 0, f(x) = 1

Replacing into the equation:

1 = 0^2 - 1

1 = -1

False, so not on the graph.

-------------------------------

(0,1)

Here, we test x = 1, f(x) = 0

Replacing into the equation:

0 = 1^2 - 1

0 = 0

True, so on the graph.

-------------------------------

(3,5)

Here, we test x = 3, f(x) = 5

Replacing into the equation:

5 = 3^2 - 1

5 = 8

False, so not on the graph.

-------------------------------

(5,24)

Here, we test x = 5, f(x) = 24

Replacing into the equation:

24 = 5^2 - 1

24 = 24

True, so on the graph.

-------------------------------

(-2,3)

Here, we test x = -2, f(x) = 3

Replacing into the equation:

3 = (-2)^2 - 1

3 = 3

True, so on the graph.

-------------------------------

(-4,-17)

Here, we test x = -4, f(x) = -17

Replacing into the equation:

-17 = (-4)^2 - 1

-17 = 15

False, so not on the graph.
