Mrs. Binders is curious to see how many days in a row students remember to bring a pencil to class. She designs a computer simulation with 50 trials and uses her data to create the graph. The graph shows the relative frequency of the number of days her students remember to bring a pencil before they need to ask for one. What is the probability that a student remembers to bring a pencil for fewer than 3 days?
