Question 11 • Algebra 2 with Probability

Suppose that 71 percent of the surface of the Earth is covered in water, and a random number generator uses latitude and longitude to select a random location on the Earth. If 6 such locations are generated, what is the probability that all 6 locations are in water?

Answer
A
0 point 9 9 9 4
B
0 point 8 7 1 9
C
0 point 1 2 8 1
D
0 point 0 0 0 6

Explanation

Each location has a 0.71 probability of being in water. For 6 independent locations all to be in water, multiply the probabilities: 0.71^6 ≈ 0.1281. Thus the probability is about 0.1281, or 12.81%, which is choice C.
