There are 52 possible selections for the card (total number of cards).
From those possible selections, only the 7's and 8's are favorable.
There are 4 sevens and 4 eights, for a total of 8 favorable cases.
Thus, the required probability is:
![p=(8)/(52)](https://img.qammunity.org/2023/formulas/mathematics/college/6zy7jmkcd455iatj46h1e9w9pgtzxoywvx.png)
Calculating, p = 0.1538
