At a particularly attractive beach in South Northland, there is a problem with sea snails, some of which are very poisonous and some of which are only slightly poisonous. Both types of snails have the unpleasant habit of biting people as they walk in the water. 2.5% of the sea snails are very poisonous and 82% of the people bit by the very poisonous sea snails have their elbows and thumbs triple in size, while an additional 2% of the people bitten by the very poisonous snails develop a desperate craving for chocolate chip ice cream. No one whose elbows and thumbs have tripled in size gets a craving for chocolate chip ice cream. The rest of the people that have been bitten by the very poisonous snails are unaffected. For the slightly poisonous snails, only 13% see their elbows and thumbs triple in size, while 29% develop a craving for chocolate chip ice cream and the rest are unaffected.

a. If someone runs up to the lifeguard and begs for a serving of chocolate chip ice cream, what is the chance that they were bitten by a slightly poisonous snail? You may assume that only those bitten by a snail crave the ice cream as no children are allowed on this beach.

b. If we anticipate 273 visitors to the beach on a given day, how many servings of chocolate chip ice cream should we have on hand (again, only for the snail bite sufferers)? You can expect each person with a craving to require one serving of ice cream, but you should have 10% of extra servings on hand for those that drop theirs when someone with oversized elbows and thumbs bumps into them.
