Question

A computer program randomly picks from the whole numbers 0–9 and lowercase letters, one at a time, to create a password.

What is the probability that the first character the program uses is a lowercase letter?

Enter your answer as a decimal rounded to the nearest hundredth in the box.

Answer 1

Your answer is going to be 0.72 :)

Answer 2

The probability is 0.72

Explanation:

There are 26 lower case letters and 10 numerals.

Given is that the computer program randomly picks from the whole numbers 0–9 and lowercase letters, one at a time, to create a password.

Means the computer picks from a total of 36 characters.

We have to find the probability that the first character the program uses is a lowercase letter. The probability becomes:

`(26)/(36) =0.72`
