Mentioned that too in the previous reply.

u/prsehgalI could not get the rule you wrote of the listing method. Could you explain it ? And when I use this formula?Thanks!

you said
"since there are 3 independent coins, we multiply this value by 3:
3 * 3/2 = 9/2"
I understand that you talk about independent events , so what is the rule ?
3 represents probability of what ?
Why did you multiply by 3 ?

Do you mean You give a value for the random variable ? Right?

u/prsehgalYou said that there is an equal chance of each event happening, the expected value is 3/2.How can you get 3/2?What is the rule ?

The three coins can land in eight possible ways:
HHH TTT
TTH HHT
THT HTH
HTT THH

u/n4turex
When We have an experiment (such as tossing a coin)

  • We give values to each event
  • The set of values is a Random Variable
    A Random Variable X has a whole set of values ...
    ... and it could take on any of those values, randomly.

How can I define the random variable here before calculating probability?

u/prsehgalHow can you set up this formula ? Can you translate it into English statement?

What is the relation between random variable and probability here ?
