2. Hacksaw's Boats of St. Lucia takes tourists on a daily dolphin/whale watch cruise. Its brochure claims an 85% chance of sighting a whale or a dolphin. Suppose there is a 65% of seeing dolphins and a 10% chance of seeing both dolphins and whales (a) Construct a Venn diagram and a corresponding two-way table for the events and give the probability of each part: (b) What is the probability of a whale on the cruise? (c) What is the probability of seeing a whale but not a dolphin?
