PLEASE ANSWER THIS AND EXPLAIN WHY. DON'T TAKE GUESSES.

Sam intends to roll a six-sided number cube 100 times.


What probability model can he use to predict whether or not each roll will give a result that is not a prime number?



Each roll has a 0.117 probability of not being prime.

Each roll has a 0.333 probability of not being prime.

Each roll has a 0.5 probability of not being prime.

Each roll has a 0.667 probability of not being prime.

Respuesta :

Each roll has a 0.5 probability of not being prime. because the prime number out from 1-6 is 2,3,5. that is 1/2 of a die. so if the person roll it 100 time, the chance of him getting a prime number is 1/2 or 0.5 or 50%.

Each roll has a 0.5 probability of not being prime (c).
The prime numbers from 1 to 6 (Because it's a six-sided number cube) are 2, 3, and 5. Those numbers are 3 numbers out of 6 total numbers; which is [tex] \frac{3}{6} [/tex] or [tex] \frac{1}{2} [/tex].

[tex] \frac{1}{2} [/tex] = 0.5 which is also 50%.
