Hel 9. Suppose that the Math Man, a super hero that fights crime with math and physics, can decelerate the rate
of gravity. During a recent fight with a diamond thief, Math Man fell from the top of a 500 meter building. The
equation:

d = t^2 x 0.25

describes Math Man's distance from the ground as he falls.

How long does Math Man spend falling if he falls?

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18}, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.
