Explanation / Answer

Answer to the question is as follows:

a. P(30 to 39) = (2835+1847+376+117)/(92+511+1631+2835+1847+376+117) = .699

b. P( not 30 to 39) = 1-P(30 to 39) = 1-.699 = .301

c. P(X<45) = (92+511+1631+2835+1847+376)/(92+511+1631+2835+1847+376+117) =.984

d. P(X>20) = (511+1631+2835+1847+376)/(92+511+1631+2835+1847+376+117) = .972
