Question 6 and 7

Ocean fishing for billfish is very popular in the Cozumel region of Mexico. In the Cozumel region about 46% of strikes (while trolling) resulted in a catch. Suppose that on a given day a fleet of fishing boats got a total of 29 strikes. Find the following probabilities. (Round your answers to four decimal places.) USE SALT (a) 12 or fewer fish were caught (b) 5 or more fish were caught (c) between 5 and 12 fish were caught Need Help? Read It Watch It Submit Answer 7.

Then use the normal distribution to estimate the requested probabilities. It is known that 81% of all new products introduced in grocery stores fail (are taken off the market) within 2 years. If a grocery store chain introduces 68 new products, find the following probabilities. (Round your answers to four decimal places.)
