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: f(2) = 5
Explanation: If f(x) - 4x - 3, then f(2) = 4(2) - 3 which simplifies to 5.
It is $84.6. You multiply 1.6 by 13 which equals $20.8. Then you multiply 3.1 by 14 which equals $43.4. Then you multiply 1.2 by 17 which equals $20.4. Add them together and you get $84.6.
