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%
Therefore, there is a 50% chance that a person will get a prime number (2, 3, or 5) with a single roll of a die, that is, with a single roll of a die, there is an equal chance that you'll either get a prime number (2, 3, or 5) or that you won't get a prime number (1, 4, or 6), i.e., 50-50.
Prime numbers on the faces of a dice are 2, 3 and 5
∴ P(rolling a prime no) = 3/6 =1/2
