PLEASE HELP WILL GIVE MEDAL! 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. 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.
There's a certain number of books, videos and magzines listed in the tally chart. To find out the probability the videos being checked out is: n of videos/n of all items in the library. So, 24/19 + 24 + 37 24/80 = .3 * 100 = 30% Thus, Brenda has a 30% chance that her first item to check out will be a video.
are you there? @arielalexis
