Answer:
Julia and Liz worked 10 hours to finish the project.
Step-by-step explanation:
I don't know if I am 100% right, but I believe this is the answer.
If you take the 24 hours it will take Julia to finish the project on her own and subtract the time it would take Liz you would have 12 hours left then take the 2 hours Liz has already been working on the project you would have 10 hours for both of them to finish the project together.
24 -12 = 12
12 - 2 = 10

Answer:
<u>The probability that the first card is gray and the second card is pink= 5/78</u>
Step-by-step explanation:
A deck of cards has a 5 pink, 2 gray, And 6 black cards.
The total cards = 5 + 2 + 6 = 13
You pick two cards from the deck without replacement.
The probability that the first card is gray = 2/13
The remaining cards = 13 - 1 = 12
The probability that the second card is pink = 5/12
So,
The probability that the first card is gray and the second card is pink =
= 2/13 * 5/12 = 10/156 = 5/78
