You roll a pair of dice. What is the probability of rolling a 2 and then rolling a 7? Answer: Probability of rolling a 2= 1/36 Probability of rolling a 7= 6/36 or 1/6 Step-by-step explanation: For this kind of probability, two things should be considered. First, how many possibilities are there in total and second, the number of times the desired outcome will occur. For example: A dice is rolled once. What is the probability of it resulting to 1? There are six total possibilities that can occur in a single roll of dice. The following are: 1, 2, 3, 4, 5, and 6 Out of all the six possibilities, 1 can only occur once; thus, the probability is equal to 1/6. Going back to the problem, a 2 dice probability chart would be very useful. I have attached a picture of sample chart I made. The cells in pale yellow color signifies the possible outcome of each dice. On the other hand, the cells in white is the sum of the outcome of the pair of dice. To answer the question: There are 36 possi...
