A solider is parachute training. He jumps out of a plane high enough that the pilot determines the solider will land somewhere in an 240 foot radius land zone. The pilow forgot to mention to the solider that the parachute has very little maneuverablity (no steering). and there are 30 trees in the landing zone. Each tree from the air practically outlines a circle with a radius of 8 feet. What is the geometric probability that the solider will land in a tree?

Answer:

Option C is the correct answer.

Explanation:

Given that an opaque bag contains 5 green marbles, 3 blue marbles, and 2 red marbles.

Total number of marbles = 5+3+2 = 10

We need to find the ODDS of drawing a red marble.

Total number of red marble = 2

Chance for getting a red marble is the ratio of number of red marbles to total number of marbles.


\texttt{Chance for getting a red marble=}(2)/(10)=(1)/(5)

ODDS of drawing a red marble = 1 : 5

Option C is the correct answer.
