Moreover, we show that on the probability space $([0,1],\mathcal {B}([0,1]),\lambda )$ the families of sequences of random variables converging in probability but (i) not converging outside a set of measure 0 or (ii) not converging in arithmetic mean are also “very large”.engjournal articlehttps://doi.org/10.1002/mana.202000102open accessLineabilityAlgebrabilityVector seriesProbability theoryRandom variableStochastic process
