What is the probability of getting 1 and 2?
Mathematically, the formula for the probability of an event is Number of outcomes for the eventNumber of total possible outcomes. Probability of 1 and 2 = Probability of (1,2) + Probability of (2,1) = 136+136=118.
What is the probability of rolling a 1 or 4 on a number cube labeled 1 through 6?
Explanation: For each number, there is a 16 probability of rolling it (so 16 for the 1 and also 16 for the 4).
