At a hatchery, the lengths of young fish in one of the tanks is normally distributed with a mean of 22.6 cm and a standard deviation of 4.7 cm. Using a TI 84 graphing calculator, Find the probabilities from randomly selecting fish out of this tank. P(A fish will have a length greater than 24 cm) = P(A fish will have a length between 15 and 20 cm) = P(A fish will have a length less than 26 cm) =
