Description
The multiplicity distribution of inclusive electron events above 4 GeV cm energy shows two distinct classes of events: two prong no photon and high multiplicity events. If the high multiplicity events are attributed to the semileptonic decay of charmed particles the two prong no photon events must come from the weak decay of a different type of particle. The charged K to π ratio was measured for these events. The average number of charged kaons is 0.07+-0.06 per two prong event and 0.90+-0.18 per multiprong event. Thus the weak current responsible for the low multiplicity events has a small coupling to strange particles. (Auth.)
