With a view to ascertaining whether the present experimental values of muon polarization P+(M/sub mu2//sup +/) and the ratio R/sub M/ = B(M/sup +/..-->..e/sup +/..nu../sub e/)/B(M/sup +/..-->.. ..mu../sup +/..nu../sub ..mu../) in M/sub l/2 decays (M = K,..pi..; l = e,..mu..) could admit a finite neutrino mass, neutrino mixings, and right-handed currents (RHC's), we have reexamined the decays with the inclusion of these factors. The polarization value P+(K/sub mu2/), admits a varied range of neutrino mass along with RHC contributions. The present values of R/sub K/ and R/sub ..pi../ do not favor Kobayashi-Maskawa mixings in the neutrino sector. Electron polarization P/sub e//sup +/(M/sub e2/), if measured, could be decisive in ascertaining the nature of neutrino mixings.
