Four workers need to label the 'sell by' date:

-Worker A labels 35% of the food items but fails to label one out of every 300;

-Worker B labels 25% of the food items but fails to label one out of every 250;

-Worker C labels 10% of the food items but fails to label one out of every 180;

-Worker D labels 30% of the food items but fails to label one out of every 150;

When a vendor complains about no 'sell by' date, what is the probability that Worker D inspected the item? What about worker A?
