Statistics
The probability distribution of the number of accidents in Grand Rapids, Michigan, each day is given by x 0 1 2 3 4 5 P(x) .20 .15 .25 .15 .20 .05 This distribution is an example of:

Pre-Calculus
Two sides of a triangle are x units and y units in length. The angle between them is theta. Prove that the area of the triangle is 1/2xysin(theta). I'm not sure how to do this question, I tried drawing a picture but I'm still not understanding it.

math
Given these sets: A = {3, 4, 5, 6, 7} B = {6, 7, 8, 9} C = {2, 4, 6, 8} List the elements of this set A(B¿C) Show work, step by step.

chemistry
At 298K, Go = -141.8 kJ for the reaction 2 SO2 + O2 in equilibrium with 2 SO3 Calculate the change in Gibbs free energy (in kJ) at the same temperature when P (SO2) = 0.505 bar, P (O2) = 0.80 bar and P (SO3) = 1.317 bar. (R = 8.314 J/K mol)
