Probability for rolling two dice with the six sided dots such as 1, 2, 3, 4, 5 and 6 dots in each die. When two dice are thrown simultaneously, thus number of event.
Probability and the 'Ways Method': Suppose we roll one six-sided die. What are the possible outcomes? What is the probabiliy of rolling a 4? If we have two dice.
There are 6 ways we can roll doubles, or a probability of or 1/6, on any roll of two fair dice. So you have a probability of rolling doubles with 2 fair. Where most go wrong is to miscalculate the sample space. At one point this exact scenario came up - Kent was planning on rolling. The probabilities vary considering what the number is. Now simply express this probability as a fraction! As the number of dice increase, then the different conditions can become more complicated.
