B 0.8 because the probability of rainy days 0.2 then the probability of sunny days is 0.8
In function notation, where f is the function, f(x)=3x-10. Using f(x) means you can write things like f(0) which means: what is the value of the function when x=0? Think of f for flexibility, because functions have greater flexibility than variables like y.
The awnser would be , 4x+4adetx
