in the French Polynesia island of France country is going according to
its 'rules and procedures' for the Pearl farmer performing it for the 
first time  then I want to know that what is the 'chance of success'

purpose would be 100% or 75% or 60% or 50% or 33% or 25% or 20% or 15%
or 12% or 10% ?? Please provide answer of my above question  and
