In the following problem, check that it is appropriate to usethe normal approximation to the binomial. Then use the normaldistribution to estimate the requested probabilities. It is knownthat 76% of all new products introduced in grocery stores fail (aretaken off the market) within 2 years. If a grocery store chainintroduces 66 new products, find the following probabilities.(Round your answers to four decimal places.) (a) within 2 years 47or more fail (b) within 2 years 58 or fewer fail (c) within 2 years15 or more succeed (d) within 2 years fewer than 10 succeed
