    May 18, 2011 · The probability that you will roll an number in each dice is 3/6=1/2. This is an AND probability: the desired outcome is to have an odd number in the first dice (1/2) AND an odd number in the second dice (1/2). With and probabilities, we multiply the two independent probabilities together, so this becomes 1/2*1/2=1/4.

Worked-out problems involving probability for rolling two dice: 1. Two dice are rolled. Let A, B, C be the events of getting a sum of 2, a sum of 3 and a sum of 4 respectively. Then, show that (i) A is a simple event (ii) B and C are compound events (iii) A and B are mutually exclusive. Solution:

Experiment 2 illustrates the difference between an outcome and an event. A single outcome of this experiment is rolling a 1, or rolling a 2, or rolling a 3, etc. Rolling an even number (2, 4 or 6) is an event, and rolling an odd number (1, 3 or 5) is also an event. In Experiment 1 the probability of each outcome is always the same.
