Hi, I have two questions which I really need help on for my grade 12 data management class. I really appreciate it thank you.

1) The lifespan of a particular turtle species is normally distributed with a mean of 180 years and standard deviation of 40 years. What proportion of these turtles will live to be more than 220 years old?

2)A company makes 2 x 4 boards that are used in construction projects. The board lengths produced by this company are uniformly distributed from 8 ft to 14 ft. Determine the probability that a board selected at random will be less than 10 ft long.
