What is the probability of getting a 10 or a 11 when a pair of dice are rolled?
The probability of rolling a total of 10 or 11 with a pair of six-sided dice is calculated by adding the individual probabilities of each outcome. The total combinations for rolling a 10 are 3 (4+6, 5+5, 6+4) and for rolling an 11 are 2 (5+6, 6+5). Therefore, the probability of rolling a 10 is 3/36 and for 11 is 2/36, leading to a combined probability of 5/36 for either outcome. Utilizing a tree diagram can effectively illustrate these probabilities.
