HELP ME PLEASE I need it no pranks

Reduce fractions expressing probability to lowest terms. in 3,000 repetitions of an experiment, a random event occurred in 500 cases. the expected probability of this event is?

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.

The function f(x)= x5+ ( x + 3)2 is used to create a table. if x = -1 then what is f(x)?
