Suppose there are say 50 observers,each observing the same particle

suppose there are say 50 observers,each observing the same particle for measuring it's properties or information,all of them choose different probability of their existence/spin out of the available states

what will be there final conclusion?

That question is ill-defined in terms of quantum mechanics. In QM observation=measurement, and you can only make one measurement at a time. The answer to your question is dependent on the specific measurements that are being carried out, and on the order in which they are carried out.

@spectracat-i don't disagree that part of observation =measurement but what if all the measurement or the act of measurement is just an event that occur simultaneously
