Hi guys, I need some help in creating a random experiment for a discrete random variable!! I can't use anything original like the "tossing a coin" example used all the time! I need something creative, new and interesting!!
It would also be appreciated if you could assign a sample space to the random experiment so i know how to come up with my own.Also if its possible could you define the random variable aswell???

in expermint of rolling  2  dice let the random variable to get a n odd summation

anonymous · Answer

hi, i also should've stated no dice experiments aswell

anonymous · Answer

ok can u give me a time 2 thnkng of plz

dumbcow · Answer

map out a circle of like 1ft radius and then drop 10 like coins or pieces of paper from like 6 or 8 ft above, and assign random variable to number of objects that land inside circle
or something like that

anonymous · Answer

okay. thats a bit complex haha. what would the sample space be?

dumbcow · Answer

for my example
0 to 10

anonymous · Answer

okay how would you assign probabilities to it?

anonymous · Answer

selection of numbered balls, 1-100, say from a bag

anonymous · Answer

sample space =100

dumbcow · Answer

umm see with mine the probabilities are unknown
most likely will follow a Poisson distribution though
you would have to base it on the experimental probilities

anonymous · Answer

ohh coz u see, in the tossing a coin exp, the probabilities can ber figured out. so it should be something similiar. but not too common

dumbcow · Answer

yeah, i wanted something unique
oh well

anonymous · Answer

mm rly sry m jst bzy now

dumbcow · Answer

use uzma suggestion
probabilities would be 1/100

anonymous · Answer

okay.so with uzma's suggestion, would there be doubles of one number or exactly one number

anonymous · Answer

exactly one number

anonymous · Answer

so for example 10 balls. the probability of getting any one ball is 1/10?

anonymous · Answer

right

anonymous · Answer

okay thanks. but i was wondering if getting different probabilities for each ball would be possible?

anonymous · Answer

look...sample space contains 10 balls
probability of selecting any ball randomly is 1/10

anonymous · Answer

if the balls r of differnt colors
let 5 are green and 5 are red
then p(green ball)=5/10

anonymous · Answer

=RAND()
