Today, the waves are crashing onto the beach every 5.1 seconds. The times from when a person arrives at the shoreline until a crashing wave is observed follows a Uniform distribution from 0 to 5.1 seconds. Round to 4 decimal places where possible. The probability that wave will crash onto the beach exactly 1 seconds after the person arrives is P(x = 1) = The probability that the wave will crash onto the beach between 1.7 and 2.5 seconds after the person arrives is P(1.7 < x < 2.5) = The probability that it will take longer than 3.22 seconds for the wave to crash onto the beach after the person arrives is P(x ≥≥ 3.22) = Find the minimum for the upper quartile. seconds.
