We investigate the contribution of 2-jet and 3-jet at Z-pole in OPAL Bose-Einstein correlation (BEC) by using the second conventional formula with two-component, as well as introducing random variables for the MINUIT method. It is found that the magnitude of the 3-jet is 1.29± 0.27 fm, which is about 34% higher than that of the 2-jet (0.96±0.01) fm. The fraction of 3-jet to all-jet is 0.18±0.03, which is consistent with an empirical value by the OPAL collaboration.
