In calculus, the chain rule is a formula that expresses the derivative of the composition of two differentiable functions f and g in terms of the derivatives of f and g.More precisely, if = is the function such that () = (()) for every x, then the chain rule is, in Lagrange's notation, ′ = ′ (()) ′ (). or, equivalently, ′ = ′ = (′) ′.
This rule allows one to express a joint probability in terms of only conditional probabilities. [4] The rule is notably used in the context of discrete stochastic processes and in applications, e.g. the study of Bayesian networks, which describe a probability distribution in terms of conditional probabilities.

Similar human chains were later organised in many East European countries and regions of the USSR and, more recently, in Taiwan (228 Hand-in-Hand Rally) and Catalonia (Catalan Way). On the 30th anniversary of the Baltic Way, a 30-mile (48 km) human chain called the Hong Kong Way was formed during the 2019–20 Hong Kong protests. [58]
Few Europeans during the period used the term "invention" for the European encounters, with the exception of Martin Waldseemüller, whose map first used the term "America".
