electron neutrinos, specifically, and all flavors of neutrinos, collectively, hence the fraction of electron neutrinos. After extensive statistical analysis, the SNO collaboration determined that fraction to be about 34%, in perfect agreement with prediction. The total number of detected 8B neutrinos also agrees with the then rough predictions from the solar model.
