Unequal probability outcomes

Outcomes are the result of flipping coins, rolling dice, or turning a spinner's arrow
List all the possible outcomes. How many outcomes are there in total?
1. A spinner with 5 parts with the colors red, blue, or yellow
2. A bag of 7 marbles with the colors blue, yellow, green or orange
Outcomes that are NOT equally as likely to occur
Write the probability in proper notation using:

$P$ $P$ (event) = $\frac{number\,ways\,to\,get\,the\,outcome}{number\,total\,ways\,of\,getting\,outcomes}$ $\frac{n u mb er w a ys t o g e t t h e o u t co m e}{n u mb er t o t a l w a ys o f g e tt in g o u t co m es}$
1. Spinning a spinner and landing on blue
2. Pulling out a green ball from a bag
3. Spinning a spinner and landing on the letter $G$
4. Spinning a spinner and landing on red
