Ahacker is trying to guess someone's password. the hacker knows (somehow) that the password is 15 characters long, and that each character is either lowercase, an uppercase letter or a numerical digit. assume that the hacker makes a random guess.

what is the probability that the hacker guesses the password on his first try? enter your answer as a decimal or a fraction.

There are 26 possible lowercase letters, 26 possible uppercase letters, and 10 possible numbers (0-9). 26+26+10=62 That means there's a 1/62 chance that they get one letter right. But there's 15 letters. They're chance would decrease each time to get it exact. 1/62 divided by 15/1 = 1/832 So there is a 1 in 832 chance that the hacker guesses it correct first try with that information.

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .

The correct answer is d, hope this
