89 10 11 12 13 14 15 16 17 18 19 20you and two friends (adam and alana) wonly play a game if it is fair for all three of you. the game your friend hasproposed to roll two number cubes (numbered 1-6) and find the sum. if the sum is from 1.4 you get the point. 5-8is adam gets the point, and 9-12 lana gets the point.is this game fair for all three of you? who has the best advantage? turn it inask for question

Well I don't know ! 
Let's take a look and see:

The idea is that there could be more than one way
for a roll of the dice to land with the same number.  

-- If the sum is from 1-4, you get the point.
There are  6  different ways for a roll of the dice to come up 1-4.

-- If the sum is from 5-8, Adam gets the point.
There are  20  different ways for a roll of the dice to come up 5-8.

-- If the sum is 9-12, Lana gets the point.
There are  10  different ways for a roll of the dice to come up 9-12.

-- The game is not fair to all three of you.
-- Lana has a distinct advantage over you.
-- Adam has a big advantage over Lana.
-- Adam has an even bigger advantage over you.
-- You are at a big disadvantage.  (Notice that one of your
numbers ... 1 ... can never come up unless one of the dice
falls off of the table.)

$12.64

Step-by-step explanation:

From the question, we are informed that Rachel finished a meal at a diner and received a bill for $10.99 and that she charged the bill along with a 15 percent gratuity to her credit card.

The total amount she charged to her credit card will then be:

= $10.99 + (15% × $10.99)

= $10.99 + (0.15 × $10.99)

= $10.99 + $1.6485

= $12.6385

= $12.64
