Find the probability that the penny turns up Tails and the die turns up "3". Click to expand... \(\displaystyle \begin{array}{cccccc}\text{For the penny:} &P(\text{Tails}) &=& \frac{1}{2} \\ \\[-3mm] \text{For the die:}& P("3") &=& \frac{1}{6} \end{array}\) \(\displaystyle \text{Since the events are independent: }\(\text{Tails}\, \wedge\text{"3"}) \;=\;\frac{1}{2}\cdot\frac{1}{6} \;=\;\frac{1}{12}\)
