Ok so there is a total of 12 marbles.
drawing a black is a probability of 3/12. drawing a red is a probability of 4:12
So first it is 3/12 and then because three are drawn instead of out of 12 it is out of 9 for red, so 4/9
3/12 x 4/9
the answer is 1/9

Answer:
6x + 102 = 1,140
Step-by-step explanation:
We're looking for the sum. The insurance cost 17 dollars per ticket, and there are 6 tickets, so we have to multiply. 17 times 6 is 102. Next, we subtract 102 from both sides. 6x = 1,038. Then, divide by 6. x = 173. So, one ticket costs 173. I don't know if the insurance is included, but if it is, then add 17 and you get 190.

Answer:
Step-by-step explanation:
a^2+6^2 = 23^2
a^2 = 23^2 - 6^2
a^2 = 529 - 36
a^2 = 493
a = √493
a = 22,20
