At an antique boat show, 90% of the boats are made of a natural, polished wood. 75% of the boats have some chrome accents on the boat on at least one visible feature. And 60% have both features.

Does it appear that having chrome accents and being made of wood are independent characteristics? Provide statistical evidence to justify your response.

They do not appear to be independent. P(wood|chrome) = 93.3%, whereas P(wood) = 90%. So
having chrome slightly increases the chances is made of wood.
