Solution

The correct sentence is: "The probability of finding the quantum particle in a volume ๐‘‘๐‘‰ at a point (๐‘ฅ,๐‘ฆ,๐‘ง) at time ๐‘ก is given by ๐œ“(๐‘ฅ,๐‘ฆ,๐‘ง;๐‘ก)๐œ“โ‹†(๐‘ฅ,๐‘ฆ,๐‘ง;๐‘ก)๐‘‘๐‘‰." This is because in quantum mechanics, the probability density of finding a particle in a certain state is given by the absolute square of the wave function, which is represented by ๐œ“(๐‘ฅ,๐‘ฆ,๐‘ง;๐‘ก)๐œ“โ‹†(๐‘ฅ,๐‘ฆ,๐‘ง;๐‘ก) in this context.
