As strange as it may seem, the easiest way to answer this question is to calculate the probability of selecting an elephant first and then to subtract this probability from 1:

Adding up the Numbers of animals, we get 12+4+3+11, or 30. The probability of selecting an elephant is thus 3/30, or 1/10.

Thus, the probability of NOT selecting an elephant is 1 - 1/10 (Answer A).

Talia is packing a moving box. She has a square-framed poster with an area of 4 square feet. The cube-shaped box has a volume

nasty-shy [4]

The volume of a cube = e^3

e = a single edge of the cube.

Area of a square = a^2

a = a single side of the square.

The volume of our cube = 13 ft^3

e = $\sqrt[3]{13}$ = 2.35 ft

The area of our square = 4 ft^2

a = $\sqrt{4}$ = 2 ft

The edge of our cube is greater than the length of our square's side.

The poster will lie flat in the box.
