Luis can fit 3 people in his car, including himself, but 5 of his friends want to 1 point
ride with him to the track meet. His friends are Tim, Maria, Lilly, Katey, and
Scott. To decide, Luis writes each of his friends' names on a separate
people of paper and selects one. If Luis picks a name 12 times and Scott's
name is picked 4 times, what is the experimental probability that Scott's
name is picked?
