← Logic & PuzzlesA distributed sensor network measures temperature and humidity; which outcome suggests temperature and humidity readings from spatially separated sensors are statistically independent?
A)Sensors share a common power source
B)Readings correlate due to air currents
C)Joint probability equals product ofmarginals✓
D)Readings filtered by same Kalman filter
💡 Explanation
Statistical independence means knowing one variable's value gives no information about the other; therefore, the joint probability of independent events equals the product of their marginal probabilities, because there's no dependency structure, rather than correlation indicating dependence or shared resources implying related failures.
