Prob(spinning a number < 3on 1 spin) = Prob( spinning 1 or 2) = 2/5
Prob( spinning <3 3 times) = 2/5 * 2/5 * 2/5 = 8/125
These events are independent so we multiply the probabilities.
The answer is (-1,-3) because the line passes through that point.
Answer: 2 because it is below 0.5 which is closer to 2 than 3
