Suppose a member is selected at random from the population and
let X denote the value of the variable x for the member obtained.
a. Determine the probability distribution of the random variable X.
b. Use random-variable notation to describe the events that X takes
on the value 2, a value of at most 2, and a value greater than 2.
c. Find P(X = 2), P(X < 2), and P(X > 2). Interpret your results.
d. Construct a probability histogram for the random variable X.

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
