Question 1036181: Arches National Park is located in southern Utah. The park is famous for its beautiful desert landscape and its many natural sandstone arches. Park Ranger Edward McCarrick started an inventory (not yet complete) of natural arches within the park that have an opening of at least 3 feet. The height of the arch opening is rounded to the nearest foot.
See the table:
Height of arch, feet 3-9 10-29 30-49 50-74 75 and higher
Number of arches in park 111 96 30 33 18
For an arch chosen at random in Arches NAtional PArk, use the preceding information to estimate the probability that the height of the arch opening is 3 to 49 feet.
