Answer: 0.55
Step-by-step explanation:
Out of the last 40 boat rentals.
22 were sunfish
10 were kayaks
8 were rowboats.
We can compute the relative frequency of each one, as the quotient between the number of each type of boats and the total number, this is:
P. sunfishes = 22/40 = 0.55
To find this as a percentage we can just multiply this by 100%.
0.55*100% = 55%.
P. kayaks = 10/40 = 0.25
The percentage will be 0.25*100% = 25%.
P. rowboats = 8/40 = 0.2
The percentage will be 0.2*100% = 20%.
Then the probability that the next rental boat is a sunfish can be estimated as the relative frequency that we found earlier, this will be 0.55.
