Answer:
1/15
Step-by-step explanation:
Step 1 find probability of pulling 1 pink marble
Like stated previously probability = # of favorable outcomes / # of possible outcomes
The favorable outcomes is what we want to happen
We want to pull a pink marble and there are a total of 3 pink marbles
So # of favorable outcomes = 3
To find the # of possible outcomes we simply find the number of marbles. There are a total of ten marbles
So probability of pulling one pink marble = 3/10
Step 2 find the probability of pulling another pink marble ( IMPORTANT NOTE: It says to find the probability of pulling 2 pink marbles if the first one is NOT put back before the second pull. this meaning that we must subtract 1 from the total # of marbles and 1 from the total # of pink marbles )
3 - 1 = 2
10 - 1 = 9
So after the first pull there would be 2 pink marbles out of 9 total marbles
So the probability of pulling a pink marble on the second pull is 2/9
Finally we multiply the two probabilities together to find our answer
3/10 * 2/9 = 1/15

Denise would have to take seven hours to charge the same amount of money as tiana. furthermore, it would cost the same amount as that is what the prompt is asking for.
to get the answer:
i subtracted $19 from $292 to eliminate the
fee element because if you were to divide
$292 by $39 without the step, the hours would be incorrect and the price would be greater.
after subtracting i got $273
from there i divided $273 by $39 and got 7 (the amount of hours it would take)
