The approximate probability that a password will have no vowels is 0.30934
The approximate probability that the first letter of the password will be m is: 0.03846
Given that we cannot use letters, numbers or symbols and this is without replacement:
There are 5 vowels in the English alphabet and they cannot be picked out of 26 letters.
So that leaves us with 21 letters
21 * 20 * 19 * 18 * 17
================
26 * 25 * 24 * 23 * 22
2441880 / 7893600
= 0.30934
For the second question, because we would have to eliminate vowels and also the letter m must be used,
1 * 20 * 19 * 18 * 17/( 26 * 25 * 24 * 23 * 22)
116200/7893600
= 0.01473
For the vowels and the first letter m.
1 * 25 * 24 * 23 * 22/ 7893600
= 0.03846
