Solution : If two dice are thrown then, as explained in the last problem, total no. of elementary events is 62 or 36. Now a total of 7 or more i.e. 7 or 8 or 9 or 10 or 11 or 12 can occur only in the following combinations :
What is the probability that the sum of two rolled dice is 9 given …
WebJul 23, 2024 · If one die A is a 4, in order for the sum to be exactly 9, die B has to land on 5. Alternatively, if die B is the one that lands on 4, then die A has to land on 5. So, there are only 2 combos that sum to 9 and have at least 1 of the die be a 4. So the probability is: (number of combos we want)/(total number of combos) = 2/36. Reduced, this is 1/18. WebYou still have to be careful, like if a problem asks what the odds of rolling a 1 AND a 2 on ONE die is, you can't roll both so the answer is 0. Or rolling a 1 on one die OR rolling a 2 … 7g plugs for ears
