What is the probability of getting 6 as a product explanation and calculation

Mrrafil [7]

For an individual die roll, the probability of rolling 6 is \dfrac{1}{6}

Effectively, this problem is asking for P(\text{1st roll is 6}\cap\text{2nd roll is 6})P(1st roll is 6∩2nd roll is 6).

Using the rule of product, this is:

\dfrac{1}{6}\times\dfrac{1}{6}=\dfrac{1}{36}
