Step-by-step explanation:

Number of digits = 10

Number of letters in English alphabet = 26

Total number of characters = $10+26=36$

Now, if replication is allowed, then the total number of ways to make a ten character password will be :_

$(36)^{10}$

The number of ways to make a password having all letters :-

$(26)^{10}$

Now, the probability that the password will contain all letters will be :-

$\dfrac{26^{10}}{36^{10}}=0.0386107708316\approx0.0386$

Hence, the probability that the password will contain all letters =0.0386
