Answer: Hello there!
initially Maria has 6 red marbles, 6 blue marbles, and 4 green marbles.
You know that in the first pick, Maria gets a green marble ( this means that now there are 3 green marbles left)
Now we want to know the probability that she gets a red marble on the second pick.
Now there are 6 + 6 + 3 = 15 marbles in the bag, and 6 of them are red ones. Then the probability of getting one red is the number of red ones divided by the total amount ( which is the ratio of red marbles to total marbles)
this is 6/15.
now you can see that there is no 6/15 in the options, so we need to see which one is equivalent.
if we took the option C, 2/5, and multiply both denominator and numerator by 3, we get (3*2)/(3*5) = 6/15, then 2/5 and 6/15 are equivalents.
Then the correct answer is C.

Answer: q=7
Step-by-step explanation:
subtract 6.4 from 25 = 1.3c + 18.6
She earns $5.50 for every hour so:

3 hours and 45 minutes is 3.75 hours.


After rounding, she earns $20.63.
1 1/3 hours. 3/4 plus 7/12 equals 1 1/3. Hope this helps
