<span>The correct answer is 67.5.
Explanation<span>:
10.4%=10.4/100=0.104.
We are finding 10.4% of an unknown number, so this gives us
0.104x=7.02.
To solve this, divide both sides by 0.104:
0.104x/0.104=7.02/0.104
x=67.5</span></span>

Step-by-step explanation:
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.

Uniform distribution from 0 to 4.8 seconds.
This means that 
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
. So




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