Question 629868: a single die is rolled one time. Determine the probability of rolling;
A number greater than3 or less than 5
Answer by Charles3475(23)   (Show Source):
You can put this solution on YOUR website! The die is assumed to have six sides labeled 1, 2, 3, 4, 5, 6. The numbers greater than 3 are 4, 5, 6. The numbers less than 5 are 4, 3, 2, 1. So the numbers greater than 3 OR less than 5 are the union of the two sets or 1, 2, 3, 4, 5, and 6. The probability of rolling one of these numbers is 6/6 or 100%.
If you meant greater than 3 AND less than 5, the intersection of the two sets is 4 and the probability of rolling a 4 is 1/6.
