Answer:

0.1419 ( (if upper and lower cases are interchangeable)

0.348 ( if upper and lower cases are distinct letters)

Step-by-step explanation:

Each digit has 36 possible choices as 26+10

computer generates six characters

there are only 26 choices for letters only, (if we assume upper and lower cases are interchangeable)

For number of letters-only arrangements = 26^{6} = 308915776

For number of alphanumeric arrangements = 36^{6}= 2176782336

In order to find the probability of letters-only arrangements : \frac{308915776}{2176782336}

=><u>0.1419</u>

Now, in different scenario if upper and lower cases are not interchangeable.

We will have 26+26+10=62 alphanumeric choices, and 52 alphabetic choices

Therefore, probability of letters-only arrangements will be \frac{52^{6} }{62^{6} }

=<u>>0.348</u>
