The probability of rolling a 6-sided die and getting a 1 or a prime number is 0.66 or 66%.
What is the probability?
The probability is defined as the ratio of number of favourable outcomes and the the total number of possible outcome.
Assuming the die is numbered 1 to 6.
To answer the question, we first need to know many prime numbers can be represented on the die. What are the prime numbers equal to 6 or lower?
We have 2, 3 and 5. (since 4 and 6 are not prime numbers). So we have 3 prime numbers, plus the number 1... so there are 4 possibilities valid for rolling a 1 or a prime number: 1,2,3 and 5.
There 4 possibilities out of 6 total possible outcomes, the probability of rolling a 6-sided die and getting a 1 or a prime number is;
[tex]\rm Probability=\dfrac{4}{6}\\\\ Probability=\dfrac{2}{3}\\\\ Probability=0.66[/tex]
Hence, the probability of rolling a 6-sided die and getting a 1 or a prime number is 0.66 or 66%.
