2 answers:
5 red, 6 blue, 4 black...total of 15
P(picking blue) = 6/15 ...reduces to 2/5
replacing
P(picking blue) = 6/16...reduces to 2/5
P(both) : 2/5 * 2/5 = 4/25 <==
Answer:
4/15 is 100% the answer *NOT* 1/9 or anything else!

The answer would be 11x-12
It would be C for personal reasons only
Every time you get 6 times out of 8 you times it like 12 16,18 24
45+(45*.15)=
45+6.75=51.75
6.75 is the tip, 51.75 is the total bill
