Answer:
It's A don't listen to the other guy
Step-by-step explanation:
Alright, here are the divisibility rules:
2 -- If the last digit is 0, 2, 4, 6, or 8.
3 -- If the sum of the digits is divisible by 3.
4 -- If the last two digits are divisible by 4.
5 -- If the last digit is 0 or 5.
6 -- If the number is divisible by 2 or 3.
7 -- Cross off the last digit, double it, and subtract. If new number is divisible by 7, the original number is divisible by 7.
8 -- If the last three digits are divisible by 8.
9 -- If the sum of the digits is divisible by 9.
10 -- If the last digit is 0.
11 -- Subtract the last digit from the number formed by the remaining digits. If new number is divisible by 11, the original number is divisible by 11.
12 -- If the number is divisible by 3 and 4.
Let's use these rules to answer your questions.

Answer:
A: 14/65
Step-by-step explanation:
Let A be the event of pulling a blue marble first, there are 28 blue marbles
Let B be the event of pulling a red marble second, there are 12 red marbles
There are 40 total marbles in the bag.
So
P(A) = 28/40
Since he pulls two marbles with out replacement, there is one less marble in the bag when he pulls the second marble, so there are only 39 marbles left, so
P(B) = 12/39
When calculating the probability of multiple events, you multiply their probabilities together, so we have
P(A then B) = (28/40)(12/39) = 336/1560
Now reduce the fraction...
112/520
28/130
14/65
Let the initial money be x so by question,
3x/5 +1x/5+1200=x
or, 1200= x - 4x/5
or, 1200 = 1x/5
or, 6000= x
hence the initial money was 6000$
