Today, the waves are crashing onto the beach every 4.5 seconds. The times from when a person arrives at the shoreline until a crashing wave is observed follows a Uniform distribution from 0 to 4.5 seconds. Round to 4 decimal places where possible. a. The mean of this distribution is 2.25 b. The standard deviation is 1 2990 c. The probability that wave will crash onto the beach exactly 3.6 seconds after the person arrives is P(x = 3.6) = 0 d. The probability that the wave will crash onto the beach between 0.9 and 2.1 seconds after the person arrives is P(0.9
