An experiment consists of rolling two fair dice and adding the dots on the two sides facing up. Using the sample space shown in Figure below and assuming each sample event is as likely as any other, find the probability of the sum of the dots indicated. --> Sum is not 2, 4, or 6. http://img146.imageshack.us/img146/1300/die1ic6.gif http://img291.imageshack.us/img291/2065/die2mh9.jpg

A card is drawn at random from a standard 52-card deck. Events G and H are G = the drawn card is black H = the drawn card is divisible by 3 (face cards are not valued). (A) Find P(H | G). (B) Test H and G for independence.

A single card is drawn from a standard 52-card deck. Calculate the probability of even and odds for each event. A king or a heart is drawn.
