Answer:   
Step-by-step explanation:
When we throw a die , Total outcomes =6
When we throw 3 dice , Total outcomes = 6 x 6 x 6 = 216 [by fundamental counting principle]
Given : Three fair dice are rolled, one red, one green and one blue.
Favorable outcomes : When the upturned faces of the three dice are all of different numbers i.e. no repetition of numbers allowed
By Permutations , the number of favorable outcomes = 
The probability that the upturned faces of the three dice are all of different numbers = 

The probability that the upturned faces of the three dice are all of different numbers  is  .

Answer:
2) 11 
3) 21 
4) 7 
Step-by-step explanation:
2) (-6) -(-17) = 17 - 6 = 11 
3) 19 - (-2) = 19 + 2 = 21 
4) (-13) + 20 = 20 - 13 = 7

Ratio means only one thing but I think what you meant was 3 examples of a ratio. In that case three examples would be:
2:3,
2 to 3,
2/3
