The following table summarizes the analysis of samples of galvanized steel for coating weight and surface roughness:
Coating weight
high
low
surface

roughness
88
34
(a) If the coating weight of a sample is high, what is the probability that the surface roughness is high?
(b) If the surface roughness of a sample is high, what is the probability that the coating weight is high?
(c) If the surface roughness of a sample is low, what is the probability that the coating weight is low?
