Define an elementary event.

Define an event

List all events associated with the random experiment of tossing of two coins. How many of them are elementary events?

Two dice are thrown simultaneously and the sum of the numbers which come up on the dice is noted. Consider the following events A = The sum is even B = The sum is a multiple of 3 C = The sum is less than 4 D = The sum is greater than 11 Which of the following is/are elementary event(s)?

A sample space consists of 9 elementary event E_1, E_2, E_3 ..... E_8, E_9 whose probabilities are P(E_1) = P(E_2) = 0. 08 , P(E_3) = P(E_4)=P(E_5) = 0. 1 , P(E_6) = P(E_7) = 0. 2 , P(E_8) = P(E_9) = 0. 07 . Suppose A = {E_1,E_5,E_8} , B = {E_2, E_5, E_8, E_9} . Compute P(A) , P(B) and P(AnnB) . Using the addition law of probability, find P(AuuB) . List the composition of the event AuuB , and calculate, P(AuuB) by adding the probabilities of the elementary events. Calculate P(barB) from P(B) , also calculate P(barB) directly from the elementary events of barB .

A coin is tossed. Find the total number of elementary events and also the total number events associated with the random experiment.

What is the total number of elementary events associated to the random experiment off throwing three dice together?
