You can put this solution on YOUR website! a. The product of each of the three, or 0.47*0.59*0.42=0.1165
b. There are 26 lower case letters and 10 digits or 36 items.
Choices are 36C6, the denominator
if digits is 10C6/36C6=0.0001
If letters is 26C6/36C6=0.1182
6/36 are vowels if one includes y, and that is 6/26 of the total, so vowels would be 0.0273
