Explanation:
There are 26 Letters in the alphabet.
In the word TOUCHDOWN, we have the letters T,O,U,C,H,D,W,N
There are 8 letters in the word Touchdown.
n(Touchdown)=n(T)=8
Therefore, the theoretical probability that the card represents one of the letters in the word touchdown
![=(n(T))/(n(S)) \\=(8)/(26)\\=(4)/(13)](https://img.qammunity.org/2021/formulas/mathematics/high-school/bpppp27aznho2l8ob49zr0nn7l8dngbdul.png)
