A probability experiment is conducted in which the sample space of the experiment is
S = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13), event F = {5, 6, 7, 8, 9, 10), and event G = {9, 10, 11, 12). Assume that
each outcome is equally likely. List the outcomes in For G. Find P(F or G) by counting the number of outcomes in
For G. Determine P(F or G) using the general addition rule.

Brittany has designed four different birdcages, each with the same volume: a square pyramid, a cylinder, a cone, and a sphere. the zoo wants to use one of brittany’s designs but plans to change the volume of the cage. find the design change that would result in the birdcage with the greatest volume. a.) increase the area of the base of the square pyramid by a factor of ten. b.) increase the height of the cylinder by a factor of ten. c.) increase the radius of the cone by a factor of ten. d.) increase the radius of a sphere by a factor of ten.
