text: a die is rolled. what is the probability that the number rolled is greater than 3 and even? i need the answer with the way you did it probability of an event is given by the formula  p=x/s, where x is the set of all the values, which result in a success and s is the set of all possible values, called the sample set now here, a die has numbers from 1 to 6. so, the sample space is 6. the number should be greater than 3 and even. first of all, the numbers greater than 3 on a die are 4,5 and 6. but the even numbers among these are only 4 and 6. so, x is 2 now probability is x/s=2/6 or when simplified, it is 1/3.
