To determine the probability of rolling a 6 on a six-sided number cube (also known as a die) two times in a row, we need to consider the probability of each individual roll first.
The probability of rolling a 6 on a six-sided die is:
\[ P(6) = \frac{1}{6} \]
Since the rolls are independent events, the probability of rolling a 6 twice in a row is the product of the probabilities of each individual roll:
\[ P(6 \text{ twice}) = P(6) \times P(6) = \frac{1}{6} \times \frac{1}{6} = \frac{1}{36} \]
Thus, the probability that Leah rolls a 6 two times in a row is:
\[ \frac{1}{36} \]
The correct response is:
1/36
