A game has a ten sided die. What is the probability of rolling a number less than 4 or a multiple of 3?

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).

The table above shows approximate conversions from gallons to liters. what is the value of x?

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?
