Question

The mail consists of 3 bills, 2 advertisements, and 1 letter what is the probability that an advertisement is opened first

Answer 1

Hello, thank you for taking the time to post your question!

There are (3 + 2 + 1) = 6 total choices, of which 2 are advertisements, so you want to take

2 / (3 + 2 + 1) = 2/6 = 1/3

Meaning the probability that an advertisement is opened first is 1/3

I hope that helps you get moving in a better direction on this type of question! Feel free to reach out if you have any additional questions beyond that :)

Answer 2

We have 6 possible outcomes and only 2 are good ones. So probability is 2/6 or 1/3.
