2. CARNIVAL In a game similar to the game in the above Example, there are
four regions in which the ball can fall. The probability that Jani can get 100 points in a
roll is 25%, the probability of 200 points is 50%, of 300 points is 20%, and of
400 points is 5%. Calculate the expected value for each roll.
(100*25/100)+(200*50/100)+(300*20/1 00)+(400*5/100)=

A) 100 B) 205 C) 2050 D) 1000

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
