1. ## Six-sided Die

A six-sided die is rolled. The sides show dots that range from 1 dot to 6 dots. What is the probability that when rolled, the side with 3 dots will appear on the top of the die?

Good reply. How did you get 1/6?

Each side has the same chance of appearing since we assume that the die is fair. The probability of attaining a "3" from (1, 2, 3, 4, 5, 6) is 1/6.

But why?

Well it can only land on either heads or tails, which means that there are only two possible outcomes. You want to know the odds of getting one of those outcomes (in this case heads). Well it's 1 out of 2 or you can write that as 1/2

In a coin there are six possible outcomes. Rolling a three is only one outcome. So there is a 1 out of 6 chance of rolling a 3, or you can write that as 1/6

Much better Quick.

I believe that good math tutoring involved more than just giving the answer.

Thanks!
