Answer 1

Brenda is training to be a volunteer at her library. She wonders what the probability is that the first item she'll get to check out for a customer will be a video. So, on her first day of training, she tracks what items are checked out. The results are shown here in a tally chart.

Brenda wrote tally marks for what type of item various customers check out. For books, there are seven groups of 5 tally marks and two individual marks. For videos, there are four groups of 5 tally marks and four individual marks. For magazines, there are three groups of 5 tally marks and four individual marks.

Use Brenda's experimental data to estimate the probability that her first item to check out will be a video. Show and explain your work.
