Answer:1/870
Step-by-step explanation:
The total number of student in Mr parietti class is 30 (18girls and 12boys). If a student is first chosen at random from the class. The probability of choosing 1 student out of 30 will be 1/30.
He then chose another student without replacing the first, the probability of choosing that second lady will be 1/29 (since the remaining students are 29).
the probability that both students chosen are girls will be 1/30×1/29 = 1/870

Answer:
Gabe needs 20 liters of the 40% solution.
He also needs 40 liters of the 70% solution.
Step-by-step explanation:
Equation:
acid + acid = acid
0.40x + 0.70(60-x) = 0.60*60
40x + 70*60 - 70x = 60*60
-30x = -10*60
x = 20 liters
Gabe needs 20 liters of the 40% solution.
He also needs 40 liters of the 70% solution.
