Question

what is the conditional relative frequency of a state's popular vote penguin by the Democrat in 2012 given that it was won by the Democrat in 1976 if necessary round to the nearest tenth

Answer 1

$\begin{gathered} \text{ We have to find } \\ P(\text{Democrat}2020|\text{Democrat}1976) \\ \text{The conditional probability is the probability of the intersection divided} \\ by\text{ the total probability of Democrat 1976!} \\ \text{thus} \\ P=\frac{\frac{12}{51}}{\frac{12}{24}} \\ P=\frac{24}{51} \\ \\ P=0.4705 \\ \text{thus the frequence is } \end{gathered}$

Thus the frequency is 47.0%
