<h2>Answer:</h2>

The theoretical probability of choosing a letter other than Z is 96.2%

<h2>Step-by-step explanation:</h2>

We know that there are 26 alphabets.

Also, the number of alphabets which are other than Z are: 25

Now we are asked to find the theoretical probability of randomly choosing any letter except Z :

It is the ratio of the number of alphabets other than Z to the total number of alphabets.

which is calculated as:

$Theoretical\ Probability=\dfrac{25}{26}\\\\\\Theoretical\ Probability=0.961538$

In percent to the nearest tenth the theoretical probability is given by:

96.2%

Probability=(number of specific outcomes)/(total number of possible outcomes)

P(!Z)=25/26 as a fraction exact

P(!Z)≈96.2% (approximation to nearest tenth of a percent)
