Question 1204199: A single 6-sided die is rolled. What is the probability of rolling a 1 or a prime number?

You can put this solution on YOUR website! A standard die has 6 possible outcomes (1, 2, 3, 4, 5,6)
Prime numbers on the face of die are 2, 3, 5.
1 is also a possible outcome. There are four favorable outcomes: 1, 2, 3, and 5.
Probability = (Number of Favorable Outcomes) / (Total Number of Possible Outcomes)
Probability = 4 / 6 = 2/3
Probability of rolling a 1 or a prime number on a standard die is 2/3,
