Explanation:
From the question we are told that
The sample size of male is
![n_m = 11 + 6 =17](https://img.qammunity.org/2021/formulas/mathematics/college/snhwlggtkyy3evh5vykna8a7zl3xpyecig.png)
The number of male Republican is
Generally the probability of getting a Republican given that a male was selected is
![P(k) = (k)/(n_m)](https://img.qammunity.org/2021/formulas/mathematics/college/h5kf5fenpfqbtqy6np8af6e6r30nxrgqk7.png)
substituting values
![P(k) = ( 11)/(17)](https://img.qammunity.org/2021/formulas/mathematics/college/s828v1icsywkx3ndm65saitbllf2j60yfa.png)
![P(k) = 0.647](https://img.qammunity.org/2021/formulas/mathematics/college/qd2blv2i5649cygfiuk70v3cukh9otm326.png)
