Question:
We roll a balanced die and look at the number obtained on its upper face, once it stops. We designate by X the random variable which takes if the result obtained is an odd number and the value if the result is even.
Determine the triplet omega A P associated with this random experiment;
define X using a table of values and then verify that X is indeed a discrete random variable;
Determine what is the probability law of X;
also determine what the distribution function of X is and graph it
Application :
We throw an unloaded die and bet on the results obtained; so that we gain:
dollars if the comes out;
dollars if the result is or ;
dollars if the result is or
Is the game fair? his hope must be zero.
