area of the pond is 50*50 = 2500 square meters
the walkway is 5 meters wide so the outside dimensions would be 60 meters by 60 meters
area of that is 60 *60 = 3600 meters
area of walkway is 3600 - 2500 = 1100 square feet
number of crates needed: 1100 / 45 = 24.44, round up to 25 crates
25 crates x $74 each = $1,850 total

Answer: 0.267
Step-by-step explanation:
The relative frequency is the number of times that we obtained a given outcome divided by the total numer of trials.
In this case we have 75 trials.
in 20 trials the outcome was a 3.
Then the relative frequency of the event "spin a 3" is:
p = 20/75 = 0.266... = 0.267
