Answer:</h2>
<em>The probability of rolling a 3 is 1/6.</em>
The probability of rolling a 7 is 0%.
<u>The probability of rolling a 3 or 4 is 1/3.</u>
<h3>
Step-by-step explanation:</h3>
The sides on a dice are 1, 2, 3, 4, 5, and 6. They all have a 1/6 chance of rolling.
So,
<em>There is a 1/6 chance of rolling a 3.</em>
<u>There is a 1/3 chance of rolling a 3 or 4.</u>
<u />
Since there is no 7 on a dice, there is a 0% chance of rolling it.
