From a survey conducted in a cancer hospital it is found that $10 %$ of the patients were alcoholics, $30 %$ chew gutka and $40 %$ have no specific carcinogenic habits. If cancer strikes $80 %$ of the smokers, $70 %$ of alcoholics, $50 %$ of gutka chewers and $10 %$ of the non specific, then estimate the probability that a cancer patient chosen from any one of the above types, selected at random is a smoker.
