Solution

single die is rolled twice. Find the probability of rolling a 6 the first time and a 3 the second time.

Solution

\frac{1}{36}

Solution steps

Find the probability of rolling a 6 the first time:

\frac{1}{6}

Find the probability of a 3 the second time:

\frac{1}{6}

Since the events are independent, Use the formula

P (X_{1} \land X_{2} \land \dots \land X_{k}) = P (X_{1}) \cdot P (X_{2}) \cdot \dots \cdot P (X_{k})

= \frac{1}{6} \cdot \frac{1}{6}

\frac{1}{6} \cdot \frac{1}{6} = \frac{1}{36}

= \frac{1}{36}
