C - 3 1/12
Get a common denominator
3*3 / 4*3 + 1*4 / 3*4
Simplifies into 9/12 + 4/12
Adds to 13/12.
12 goes into 13 1 time, leaving us with 1 1/12
Add the 1 to the 2 full cups that already existed in the original problem - 3 1/12
Multiply .15 by 24 to get your answer. The answer would be 3.6 which is $3.60 as your tip

Answer:
the answer is 5/33
Step-by-step explanation:
Total marbles = 5 blue + 4 red + 3 yellow = 12
Two marbles are selected, first is blue which gives us :
5/12 --eq 1
Then red marble is selected ( note: one marble is already drawn and not replaced so we have a total of 11 marbles )
The probability of red gave us :
4/11 --eq 2
Now we multiply eq 1 and 2
5/12 x 4/11 = 5/33
