If you roll a six-sided die, what is the probability of rolling a five or an even number? *
mars1129 [50]

Answer:

The probability would be a 4/6 or 66.67%

Step-by-step explanation:

All of the even numbers (and five) on a six sided die are 2, 4, 5, and 6.

That is four total numbers.

Also, since there are <em>six sides</em> on the cube, you would have a 4/6 chance or 66.67% chance of rolling a 2, 4, 5, or a 6.

Hope this helps!!!!!!
