In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
table swimmers and runners
Step 02:
survey (percentage):
runners and prefer chocolate milk:
chocolate milk (runners) = 89
total runners = 135
% runners and prefer chocolate milk = (89 / 135) * 100 %
% runners and prefer chocolate milk = 65.9 %
The answer is:
66%
