    Chi-Squared Distribution Question

    I've attached the problem statement, and used R to find these probabilities. I got to part b, and my probabilities aren't decreasing however, so I'm wondering what I did wrong if anyone can see it.

    n=10
    > r<-1- pchisq(45,9)
    > (36*r)/9
    [1] 3.690651e-06

    n=25
    > r<- 1-pchisq(45,24)
    > (36*r)/24
    [1] 0.008737591

    n=50
    > r<- 1-pchisq(45,49)
    > (36*r)/49
    [1] 0.4672508
