Dear Maple users

I am unsure how to handle events and their probabilities in Maple. Let's say I know that an event A has the probability say 0.3 and another event B has probability 0.8. I would like to make the following assignments:

P(A):=0.3:

P(B):=0.8

and maybe defining the conditional probability:

P(A|B):=0.55

but I am not allowed to do so in Maple because if will regarded as a function definition. My purpose is to make simple calculations with those probabilities for example:

P(C):=P(A)*P(B) etc.

My problem is therefore more of a notational problem than a mathematical one. I hope someone can advice me on a proper setup. I am using 2D math notation, by the way. I could of course name the variables containing the probability using simple names like X1, X2, etc., but then I need constantly to remember what they really mean. The above assignments would be much better, because they are easier to handle mentally.

This should be trivial but I am not able to figure out the right syntax to execute it

The pdf is given by :

f_X(x)={ 1/25 *x, 0<=x<5

2/5 -x/25, 5<=x<10

0, otherwise

I have tried to use the "CumulativeDistributiveFunction" so far

Hello people in Mapleprimes,

I want to do calculations about an expected value.

For example,

expectedvalueofc.pdf

that is, \int_a^b c d \Omega

where, \Omega is a distribution function of c.

But, I don't know whether this equation can be put into worksheet.

Is there no way other than writing this as

\int_a^b c g(c) dc,

where g shows a probability density function.

Can I use Statistics[ExpectedValue] to calculate expected value with a general distribution function, not specified

to normal distribution?

I hope you will give me some hints.

Best wishes.

What is the probability that the total of two dice will be greater than 9, given that the first die is a 5?

Please I want to know how to solve this integration.

int(exp(-(ln(y)-2*sigma^2)^2/(8*sigma^2))/(y*sqrt(8*Pi*sigma^2))*exp(-(ln(y+z)-2*sigma^2)^2/(8*sigma^2))/((y+z)*sqrt(8*Pi*sigma^2)), y = 0 .. infinity)

How can you create a loop for Monty Hall Problem when you have 3 door (1 opening) and then 4 Doors (with 2 openings and possible 2 switches)

Hi,

I need help formulating a biased coin toss.

I want to toss a coin 0 being heads and 1 being tails with probabilty 0.495 of getting heads, how do I show whether heads or tails wins??

Thanks

Hello,

would you please help me how can i introduce a probability distribution function to maple in document mode?

I want to calculate integral of x f(x)dx, while I want maple to know f(x) is a probability distribution function.

I do not have any assumption about f(x)(for example normal or exponential distriburion)

In a pocket, we have balls number from to

Let X be the random variable uniformly distributed in the disk centered at the origin O(0,0) with radius 1 and let Y be the random variable uniformly distributed in the square having its vertices A(6,-1), B(9,-2), C(8,-5), and E(5,-4). What is the PDF of the distance between X and Y? Is it possible to find that with Maple? The similar question in three dimensions, replacing a square by a cube and a disk by a solid sphere.

I need to integrate the Student-T function which is a function of two variables (nu and t). Maple allows me to use this function through this command:

with(Statistics);

PDF(RandomVariable(StudentT(nu)),t);

The integration of this function gives me the probability (p) of certain event (nu is already known):

p=Int(Student,t=-infinity..X)

If I provide the value of X I can compute the integral easily, now the problem appears when I want to...

I can define a discrete, finite universal set U, say the digits 1-5.

U:={1,2,3,4,5}

I can define a subset such as

X:={2,4}

Maple will compute the complement

U\X

but I cannot find any common textbook way of naming that complement that Maple will accept. I cannot use a superscript c. I cannot use a prime. I cannot use an apostrophe. I cannot use an overbar. Yes, I can type any of those using the various symbol...

dicing-with-death-chance-risk-and-health (Stephen Senn)Mr Brown has exactly two children. At least one of them is a boy. What is the probability that the other is a girl? What could be simpler than that? After all, the other child either is or is not a girl. I regularly use this example on the statistics courses I give to life scientistsworking in the pharmaceutical industry. They all agree that the probability is one-half.So they are all...

I need more help with code please!

A box of candy hearts contains 52 hearts, of which 19 are white, 10 are tan, 7 are pink, 3 are purple, 5 are yellow, 2 are orange, and 6 are green. If you select 9 pieces randomly without replacement, what is the probability that A_3 of the 9 are white, and B_3 of the 9 are white, 2 are tan 1 is pink and 1 is yellow and 2 are green

19 Whites in the pack / 52 hearts in the pack = .3654 possibility of picking a white from 1 draw.

I've tried using Maple Help within the Maple software, but it is not very user friendly. Nothing seems to match up when I type the commands that it tells me, I always get an error. How do I find the moment generating function from a probability density function (pdf)?

Thanks.
