Systematic uncertainties in the light-element abundances and their evolution complicate a rigorous statistical assessment. However, using Bayesian methods we show that the following statement is robust: The predicted and measured abundances are consistent with 95% credibility only if the baryon-to-photon ratio is between 2{times}10{sup {minus}10} and 6.5{times}10{sup {minus}10} and the number of light neutrino species is less than 3.9. Our analysis suggests that the {sup 4}He abundance may have been systematically underestimated. {copyright} {ital 1995} {ital The} {ital American} {ital Physical} {ital Society}.
