A and B are discrete random variables. A can take on one of 20 possible values. B can take on one of 64 possible values. (In oth

er words, the size of domain ( A ) is 20, and the size of domain ( B ) is 64.) How many possible outcomes does the joint distribution P ( A, B ) define probabilities for?

Answer:

It defines 1280 possible outcomes

Step-by-step explanation:

A can take on one of 20 possible values.Then, B can take on one of 64 possible values

The form to choose these pairs of outcomes are

(Possible values from A) x (Possible values from B) = 20 x 64 = 1280

Also the sum of these 1280 pairs of values must be equal to 1 because P(A,B) it is a joint distribution of probability.

We sum this 1280 pairs of values because A and B are discrete random variables.Otherwise we would use integrals.

hello

to solve this question, we need to use know the number of possible outcomes

\begin{gathered} \text{probability = }\frac{nX}{nS} \\ S=\text{  number of possible outcomes} \\ X=\text{ number of events} \end{gathered}

let's find the number of possible outcomes

we have four tiles numbered 1, 4, 5 and 8

possible outcomes are

Find the volume of the pyramid below. Hint: The base is a right triangle, so you will need to find
Aleks04 [339]

<u>Given</u>:

Given that the height of the pyramid is 12 units.

The base of the triangle is 8 units.

The height of the triangle is 6 units.

We need to determine the volume of the pyramid.

<u>Area of the triangle:</u>

The area of the triangle can be determined using the formula,

A=\frac{1}{2} bh

where b is the base of the triangle and h is the height of the triangle.

Substituting the values, we get;

A=\frac{1}{2}(8)(6)

A=\frac{1}{2}(48)

A=24

Thus, the area of the triangle is 24 square units.

<u>Volume of the pyramid:</u>

The volume of the pyramid can be determined using the formula,

V=\frac{1}{3}AH

where A is the area of the triangle and H is the height of the pyramid.

Substituting the values, we get;

V=\frac{1}{3}(24)(12)

V=\frac{1}{3}(288)

V=96

Thus, the volume of the pyramid is 96 cubic units.

A fair coin is tossed three times and is tails each time. What is the probability that the next toss will be
Sergio [31]

The probability that the next toss will be heads is 1/8.

<h3>What is probability?</h3>

The likelihood of an event occurring is described by probability. We frequently have to make forecasts about the future in real life. We may or may not be aware of the outcome of an event. When this happens, we declare that there is a chance the event will take place.

Using the probability formula, one can determine the likelihood of an event by dividing the favorable number of possibilities by the total number of options. Since the favorable number of outcomes can never be greater than the entire number of outcomes, the probability of an event happening can range from 0 to 1.

Probability of getting two tails and next heads in three tosses is,

=1/2*1/2*1/2

=1/8
