B. 19.5%
C. 33.4%
D. 16.6%

Determine the mean and variance of the random variable with the following probability mass function. f(x)=( 729divided by 91) (1 divided by 9) superscript x baseline comma x equals 1,2,3 round your answers to three decimal places (e.g. 98.765).

For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)
