Answer:
80%; 30%
Step-by-step explanation:
There is 5 blue marbles, 2 black marbles, and 3 red marbles. In other words, there is a total of 10 marbles.
There are only 2 black marbles and 8 marbles that are not black. Therefore, the probability of <em>not</em> drawing a black marble is 8/10 or 4/5 or 80%.
There are only 3 red marbles out of the 10 total marbles. Therefore, the probability of drawing a red marble is 3/10 or 30%.

Answer:
Step-by-step explanation:
observe by inverse definition of a function
Surface area is the area of the surfaces
the areas are
base
2 triangles (faces)
2 rectangluar sides
solve
area of base=legnth times width=16 times 9=144
area of 2 triangles is 2 times 1/2 times base times height=2 times 1/2 times 16 times 6=1 times 16 times 6=96
area of 2 rectangles=2 times legnth times width=2 times 10 times 9=180
total area=base+2 triangles+2 rectangles
total area=144+96+180=420 square inches
the answer is 420 square inches or B
