Today, the waves are crashing onto the beach every 4.8 seconds. The times from when a person arrives at the shoreline until a cr
kaheart [24]

Answer:

61% of the time a person will wait at least 1.872 seconds before the wave crashes in.

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

P(X \leq x) = \frac{x - a}{b-a}

Uniform distribution from 0 to 4.8 seconds.

This means that a = 0, b = 4.8

61% of the time a person will wait at least how long before the wave crashes in?

This is the 100 - 61 = 39% percentile, which is x for which P(X \leq x) = 0.39. So

P(X \leq x) = \frac{x - a}{b-a}

0.39 = \frac{x - 0}{4.8 - 0}

x = 4.8*0.39

x = 1.872

61% of the time a person will wait at least 1.872 seconds before the wave crashes in.
