Hello!
When we roll a dice, we can get six different possibilities, that are:
{1, 2, 3, 4, 5, 6}.
Knowing it, let's answer your question:
First, let's calculate the probability of rolling 2 the first time:
[tex]\frac{\text{possibility that we want}}{\text{ total of possibilities}}=\frac{1}{6}[/tex]Note: there's only one chance in six to obtain 2 when we roll a dice.
Now, the probability to obtain 1 the second time:
As I mentioned, there's only one chance to the
