Answer:
When throwing a single die, there are six (6) possibilities or outcomes: 1, 2, 3, 4, 5, or 6.
On a single die, there are the three (3) prime numbers or successful outcomes: 2, 3, and 5.
Therefore, ...
The probability of getting a number that is prime with a single roll of the die = Total number of successful outcomes/Total number of possibilities
= Total number of prime numbers/Total number of possibilities
= 3/6
= 1/2
= .50
= 50/100
= 50%
